- 👉 Learn about the parts of a parabola. A parabola is the shape of the graph of a quadratic equation. A regular palabola is the parabola that is facing either up or down while an irregular parabola faces left or right. A quadratic equation is an equation whose highest exponent in the variable(s) is 2.
The parts of a parabola include: the axis of symmetry (the line passing through the vertex of the parabola to which the parabola is symmetric about), the vertex (the point at which the parabola turns), the domain (the set of possible x-values of the parabola, usually all real numbers for regular parabolas), the range (the possible y-values of the parabola which is usually the region above the vertex inclusive or below the vertex inclusive for regular parabolas), the x-intercepts (the points where the parabola cuts the x-axis) and the y-intercepts (the point(s) where the parabola cuts the y axis.

its 15 not -15
you are correct, thanks!
Thank you for the videos. They helped me get through my summer math class.
I saw it too. Maybe it's because he was moving a bit fast he first realise
so is the minimum 2 and maximum 15?
@@daptoperchen9484 brother the coordinates of the maximum point is (2, 15)
The savior of quarantine math homework
yes lol
Amen
David Evangelista omg yes
and tests....
Amen😂😂
Who else got a test tomorrow 🤷♂️
here
midterm for me
Exam tomorrow lmaoo
Test on Monday
I have it today goodluck to me
You're like literally my math teacher at this point. Love your videos! (Precalc)
happy to be there for you!
this guy deserves all of these positive comments, ive never seen a math teacher so well versed he created a MASSIVELY sucessful youtube channel based ENTIRELY on math
He’s a good teacher 😊
Thank you very much “teacher” I really appreciate it and you are very helpful
Your the best online teacher so far i found in internet thank you i learned a lot from your youtube videos... Im not actually liking your vids but since i found your channel I've never been into another yt channel.... Thank you
I like the way you deliver the topic it's always straight to the point. Best math teacher love your work❤👍👍👍
this explanation is 10x better then the ones my teacher gives
happy to help!
Let's admit it, this is the best math teacher you can ask for
He teaches so well. It feels like I'm in a real class.👌
Man wish this guy was my math teacher
You are a God send sir. Your getting me through pre-cal
I cringed when he made the mistake and spent the last few seconds of the video sincerely hoping for him to realise it! 😀😀😀
Great tutorial, though...
What if you have a function x(y) instead of y(x)
thank you so much I'm subscribing to your channel please post more video you are such a great instructor, used very detailed and quick explanation.
Thanks Ikram! Post everyday
Good for your students 👏 👍🏿 😀 🙌
Thank you very much you make things easier cuz you explain it better than my teacher ❤
Id tag my professor if I could
How did you get -15 for the "y" value? I came up with 15.
This wasn’t in our unit but it’s on the final tomorrow 🤷♂️
anddd same
This guy and the organic chem teacher has been carrying me from high school and college lol
this guy is saving me from functions rn
you literally teach better than my algebra honors teacher 😬
Thanks for the help. Half falling asleep doing my homework, so this helped me... stay alive.
Anyone else here under 16 currently doing this for GCSEs?
y=positive 15
what is the formula for minimum point . Thanks
tf why does this make sense more than the way my teacher explains it?
Every comment on a youtube video about math: - U explain better than my teacher. My teacher takes 1 hour, while u take only 10 minutes.
Real teachers after reading this: - Am I a joke to u?
Thank you very much sir this helps a lot
i would also recommend changing the equation into vertex form to find the vertex, which seems easier to me
NOOB
vertex from is for babys!
this guy saves life ong
thank you brian mclogan
Everyone-watching solution
Le me - 𝙩𝙝𝙚𝙮 𝙝𝙖𝙫𝙚 𝙖 𝙡𝙤𝙩𝙩𝙩𝙩 𝙤𝙛 𝙢𝙖𝙧𝙠𝙚𝙧𝙨𝙨𝙨𝙨𝙨𝙨
Thanks
Thanks ❤
Y is positive 15
So, this equation has the maximum value not the minimum which ( 2, -15) or only (-15)?
It’s actually supposed to be 15
Thank you so much Sir !
the way he writes minimum and maximum omy
Thank u sooooo much sir
you are very welcome!
15
who else is watching this while taking a quiz 😬
Are you spying on me
Jk but yes I have a test
Those who dont know how he got 15,
-8+16+7
Add -8 to 16 = 8
Than add 7, 8+7= 15
(He made a mistake by writing -, its a positive) hope this helped!!
My brain thinks that the word “Math” means sleep so everytime in math class i would feel very sleepy and cant focus and so here i am
Strange how NONE of the student noticed the mistake...
Its maximum not minimum right
trick or treat
no
They are learning how to do it.
@@johnsherby9130
Watch bawa's proof of pythagoros theorm
@@johnsherby9130 learning how to do it??? Did you even understand what are we talking about here? -8+16+7=!!!
you explain things so much better than my teacher
in 2024. it is still a important topic
The way he wrote minimum was so satisfying 1:08
1:09
SO TRUE!
🤤
lifesaver, my teacher sucks at teaching online, and in the classroom.
facts!
You’re such a great teacher. I’m having a hard time in my math class. You are really helping me so much!!!!!
We should study
I dont even understand it :(
Hello
Where are you from
can you provide the exact notation of the question, I am having a hard time understanding exactly what you are asking. In the video above I show how to find the maximum or minimum value of a quadratic
Brian McLogan is -15 or 15 can you make sure
@@ahmedthabit579 it's 15 lol
But it's 15 not -15
As of now, the 160 dislikes are the people that didn't realize that it was supposed to be 15 and not -15.
Which is why they failed :p
it must be a blessing to be in his class he teaches so well!
Brian I just want say, any time I have a math question, you’re the first person I go to. And you ALWAYS deliver! I looked this up thinking, “nah I ain’t gonna get lucky”. Then boom. First video.
Thank you king 👑
Boom love it
I love his hair line
How do you find the range if it is a maximum value pls anybody
it's a max if a is more than zero. in this video a is less than zero, hence there is a min value
Thank you for you videos! I'm learning by myself actually, because my teacher is helpless....
Thank you I'm in a test full of this and my teacher didn't say anything about it
Your videos have saved me. I get too nervous in class and end up not asking questions, and the teaching style of my teacher is hard to understand to me. Your videos are quick and easy to understand :)
Sir We can determine y= f(x) ( max / min ) by putting dy/dx = 0 and then substituting the value of x ( --b/2a ) in y . DrRahul Rohtak Haryana
watching in 2020, this really helped me in my calculus module Q^Q thankyouuu
hahaha even though he made a mistake still I learned a lot from this, what a perfect teacher. Thank you
What is so funny??? hahahah Idiot!
@@umbnmbu4679 ssh
MAXIMUM is y=15
can the "c" in ax²+bx+c be a negative number? even with the plus sign for c?
Yes it can
Test on Friday and I don’t understand anything ;(
I have dyslexia and this helped me finally understand
Me watching this at 1 AM with a test in the morning:
I love this man. He explained it so well and easier than how my math teacher explains it (actually, my teacher does not even explain it. Just shows what he’s doing and expects us to just get it.)
Hahaha exactly like my teachear
thanks, I have a math test tomorrow, and didnt really understand this, I hope that now that i know this i can get an A!
I have a math test today so thanks for helping me
So the coordinates for both x=2 & y=15 are the vertex coordinates, and also the line the axis of symmetry pass through?
1 hour of math class in school: Zzzz
4 minutes watching your video: OMG easy bro GGs (thank you for your help)
Thank you so so so so much! I have a quiz tomorrow and my teacher told me to figure it out in my own, I was so confused and this is so simple!
what about maximum value of (x) / (x^2 - 5x + 9) ?
minimum value brother
Are graphs written in ax^2 + bx + c like what you just did just open up or down, and not left or right?
Love your channel, thanks!
no there can be up down, left right all depends on the values of a,b,c. That is why using vertex form is helpful
@@brianmclogan but in the standard form x is raised to 2, right? Does that automatically mean the graph would either open up or down if x^2, while if the y value is raised to 2 then the graph would open left or right, is that correct?
that is correct, in standard form and vertex for x^2, however if you are looking at the parabola in conic sections then y^2 is a sideways parabola
@@brianmclogan oh, okay I get it. Been studying for a college entrace test and you and your videos been helping a lot! Thanks!
awesome! happy to be able to help
this video was super helpful, i was stuck on this forever until i saw this video
Bambaclatt this was so easy, also its crazy to think that i was 6 when this video was uploaded
Super amizing good because of your vlog tutorial I got some knowledge from you so
Guys its already written (mistake) I don’t know why u can’t stop saying it’s wrong like it’s already written in the title
I'm almost in tears why are math teachers so horrible 😢 this is so simple but they try to make it as complex as ever in class. I love you man😊
yeah you got the -15 and 15 mixed up cuz -8+16+7= positive 15 not negative
Another way to get y=-d/4a that is d=b^2-4ac
could it be a maximum and a negative Y ?
U saved my ass with that formula
Tomorrow, I'd be writing my last math exam in my life. Thanks for this.
How was it?
@@shawn651 it went well. Thanks for asking.
Just a question what about the exponent of 2 for a?
Fate should have made you my teacher. Looks like I will have a regret in my life.
Thanks man this helps a lot
The students are blessed in this class
Ur the reason I'm passing my math classes
Thanks professor, that was really helpful!
Hello professor.you are really helping me.god bless you.
i think -8+16+7=15 not negative 15.
How did you get that like in general, where did the 15 come from
How did you get -15, shouldn’t it be positive 15?
Sir I thiink its 15 not -15 because -8 +16 = 8 +7 = 15
Should I just pay u my school fees cuz u teach me way more than my teachers…
Thx for the help man!
Maximum value must (-2,15)
I thought it was a minimum value since a is less than 0
And also it is (2,15)
Hey , i don't understand how you got your y...
It's 15 not -15 because -8+16+7= 15.
Good job.
