- 👉 Learn all about graphing exponential functions. An exponential function is a function whose value increases rapidly. To graph an exponential function, it is usually useful to first graph the parent function (without transformations). This can be done by choosing 2-3 points of the equation (including the y-intercept) and plotting them on the x-y coordinate axis to see the nature of the graph of the parent function. After graphing the parent function, we can then apply the given transformations to obtain the required graph.

is n't the range ( 0,infinity)
yes I used to have an annotation for it but it was deleted so your commend is pinned so others that catch it

خف بق اسيلايل
i had a test today and your comment saved my life
yeah
I was about to say the same thing
This was explained better to me in under 10 minutes than when my teacher tried to explain it to me in 50 minutes
: ) happy to be able to help you out!
istg
You are absolutely right
Dude you are so good and structure. This is where most math teachers fail.. or at least mine. She jumps around a lot. Math need to be straight to the point from a -> b with steps by steps solution. Mine she jump in the process of finding the answer instead of writing it out step by step
thank you, happy to be able to assist you
I finally understand 😭 almost cried at the library when it clicked. Thank you so much
The dude has serious mad teaching skills!!
yukii : ) thanks
yukii so ur 4 years older now does math get harder
@@tinymajor214 ofc it does lol
I take online classes, where no one really teaches you how to solve a problem, it just tells you the next outcome. Where as when I watch these, I get an explanation and more realistic examples that would show up on quizzes. So these videos truly do shed some much needed light.
I took Algebra 2 years ago and was expected to remember everything as I had to take Algebra 2 because I decided to finally graduate high school. Your channel really helps prevent me from having anxiety attacks from the pressure of failing. So thank you!
2020 here i used whole day try to understand this but u use about 10min to make everything clear for me!
Damn I can't stop watching these! You're seriously so good at explaining math, this totally just helped me with exponential functions. Thank you
awesome! happy to be able to assist you!
You, Mr. McLogan, are an EXCELLENT explainer. Thank you for all your videos.
I'm a day behind on my assignments and I was confused about asymptotes still, but this certainly clarified things, and thankfully your community w/ their comments has also enlightened me, so thank you and the rest of y'all. Great video.
awesome! glad to hear
I just wanna say thank you because I have been struggling in my math class all semester, our college is doing only hybrid classes aka we do not have a teacher that will give us a lecture on the concept we just rely on 5 minute videos that do not help at all. You might've just been the reason I wont fail this class!! Thank you thank you thank you
you are very welcome sara! happy to be able to help you out
Your videos are saving me right now. I'm in my first year of college and math has been my biggest hurdle. Your videos are concise and clear. Thank you!
best maths teacher !!! i study in the uk and my teacher hates me
sorry to hear about that Yasameen but happy to be there for you
Man, this has helped me so much! I finally feel confident in math because of your videos
awesome! happy to be able to help you out!
I Just wanted to say thank you so much. My parents made me do online geometry over the summer, but because of covid they had to shorten the year, so I ended up taking a 9 month class in 5 weeks with only 2 hours a week with you teacher. Your videos were one of the only things that got me an A.
Thanks for correction on the range. I love your videos and share with my students often - I was seriously second-guessing myself so thanks for the pinned comment :)
Very straightforward instruction. Top notch. Thank you.
Brad E happy to help!
This is better than my mom yelling at me.
The range should be 0 to positive infinity.
thank you so much! You are so right, not sure what happened, but I corrected it with an annotation
Thanks!
In a few days, I will have an oral exam. This video really helped me. Thank you so much
Better than Khan Academy and any other online tutoring videos I could find. Thank you for being so clear and answering all the questions I had!
you are very welcome! very happy to help
This man right here just helped me completely understand why these problems work the way they do. My professor needs to be this man.
well I am here for you all the time online
thank you s much!!:)))) May God bless the works of your hands.
Thank you for posting this video :-)
you are very welcome! happy to help
Thank you so much! GCU Math 154 was killing me, then I found you! Thank you!!!!
wouldn't range be (0, infinity)
Michelle Moore you mean y>0?
TinyMajor214 your 6 years late
Chris you’re 2 months late
TinyMajor214 2 months doesn’t compare to 6 years
Chris okkk buddy
Good teacher makes it all so simple
Would writing the range as {y|y>0,y∈R} correct as well? I wrote Y greater than Zero because I'm thinking the graph would never get to zero..
I really appreciate your videos. Thanks Mr. McLogan!!!!!!
+Grant Morgan You are very welcome!
Great explanation despite the glitch at the end.
Amazing and very helpful video. Congratulations! Keep up your great work
I have watched so many videos from u this semester that I feel like I know u
Im currently in calc 3 and until this video Ive always had a hard time understanding exponential functions. thank you, this is what ive been needing.
This was an awesome video! I understand it so much better now. You're really good at explaining math compared to my teacher. One thing, can you explain how you find the asymptote? Is it always going to be y = 0?
unless you have a vertical shift then it will be y=k as y=(a+h)^x+k
@@brianmclogan So basically for every horizontal asymptotte, the asymptote will be 'y=0'?
Thank you for explanation without beating around the bush
Thanks so much I was struggling with the powers but this has helped me figure it out now :D
I wish this guy was my teacher ;_;
Lol he is so passionate from the way he teachs
☺️☺️☺️
Godly teaching skills man. Thanks for all the help.
you are very welcome! happy to help
Thanks he’s a life saver 😩
Thank you!!
Thank you soooooo much sir!!! I needed this!
Thanks for posting this video! I struggle in calculus and this is really helping me.
awesome! happy to be able to assist you
Omg thankyou so much I finally get this
You have saved my grade in math.
This help me more than my math honors teacher, she can’t explain the problem or the lesson
sorry to hear but happy to be able to help!!!
Thank you for posting this video
Your explanation makes me know all about math. thanks guys
you are very welcome!
Thank you comrade
Thank you so much😊😊
Needed this thank u 🙏
When Brian faces the board, I see a parabola. Sorry, I think you're a great teacher. I just couldn't help myself. ;-)
Thank you so much !!!
For real .. thanks so much !!! Have been trying to understand that for almost forever.. keep up saving our grades pls xD
Will do
My savior
Thank you sir this is pretty helpful
Nice video! It helped me a lot!
thanks! happy to be able to help!
Thankyou Sir😊😇
Thank you
You’re the best
Sorry, but can you make a Transformations and Radical Function video that shows how to find domain and range? I really need it. I could not find it anywhere in your videos.
I have oral exams in a few days, which will help me.
it really helped me a lot❤️
You are amazing
You're my hero
So... is the horizontal and vertical asymptote both zero?
Very good explanation but can someone explain what the asymptope would be for a negative line?
I cant find a single video explaining exponential functions the same way my teacher did it. When she would tell us to graph exponential functions, we use the "magical points" (-1,1/b) (0,0) (1,b) and then use x/k+d and ay+c to find the transformations and then graph it and find domain and range. Any videos that explain this?
Alternate title: man teaches math while refusing to look at a camera
YOU have saved me
happy to be able to help !!!
Isnt the domain (0, infinity)? Becasue it approaches 0 but it never gets into the negatives?
How to know if the asymptote is horizontal or vertical pls answer
can you also give fraction values for x?
Since they are real numbers.
Thank you!
yeey! thanks sir!
Is the range going to be 0 to infinity for every equation? Or is it the asymptote to negative infinity every time?
I made a mistake it is 0 to infinity
SIR, I WISH YOU WERE MY TEACHER
i wish u were my math teacher
I would'nt be one youtue if i had a teacher like him
range is (0,∞)
Is the asymptote ever not 0
Abigail Paquet yes if there is a transformation
Abigail Paquet also thank god for his guy he is saving my grade
didn't understand how you got the range values. Shouldn't it be from zero to positive infinity?
Yes
hi. what grade level is this intended for ?
4:54-5:00 cracked me up so hard ik it's dumb but still
sana ol may whiteboard marker
Why the range is negative where it is the output of the function? I don't understand. Please help me.
+Hossain Adoor I made a mistake the range is (0,infinity)
You wrote the wrong range right at the end of your video:(. You wrote (-inf, 0) when it was supposed to be [0, inf). I wanted to use your video for my students during our stay home mandate, but that would totally confuse them at the end:(.
The range must be (0, infinity). Right?
Can you explain why the horizontal asymptote of f(x)= 2^x -3 is f(x) = -3? Thank you.
because the graph is shifted down 3 units, and the graph f(x)=2^x has a horizontal asymptote at y=0
Thx
يلبيه المحنه
you are very welcome!
What about when they don't have exponents?
thanks
you are very welcome!
How would you determine the asymptote for an exponential function that has been transformed? Without a graph.
no that the graph has an asymptote at y=0 so whatever the transformation is will just move the asymptotes as well
y intercept isn't always 1 because the graph may have been shifted horizontally
correct, I should had clarified better
if the function cant reach the asymptote then how come the domain is from -ve infinity???
+desperate housewives fanpage domain is the set of all x-values. the asymptote only affects the y-values as the graph can continue to extend infinitely left and right
Range = (-oo, 0) ?
I expect better from you Brian.
He got that wrong. On the Exponential function the rage is ( 0, positive infinitive).
Vander G Dos Santos correct I stated it wrong, that is why I created an annotation to fix my error, thank you for letting me know!
thanks bro
you are very welcome!
Helped
awesome!
Oops! The range of the exemplary function is (0,infinity), not (-infinity,0).
So range is (0,infinity) right?
yes, my mistake it is noted in the comments
ik this is an old vid but isnt the range supposed to be: (0,infinity)
Yea check the pinned comment
