You sir are a Godsend to all of use that hate learning the "old-school" way that involves a teacher explaining boring concepts in the most boring manner possible. Keep up the good work.
Thanks for seeking outside help and choosing this channel to learn from! ...and thanks to that "old school" way of teaching I continue to have a job and one that I love and enjoy monday thru friday...BAM!!!
ive been using your instruction for about a year now while studying math. youre creating the model that all instruction will move to. this method of media also allows those who wouldnt attend college for whatever reason to become engaging and redefine what employers look for in qualified individuals. new videos look awesome by the way
Thanks for being such a loyal viewer josh thompson and taking the time to share your experience and thoughts for the future...as long as parents keep teaching cursive writing at home I think I'll be around for a while yet:) Don't forget to like, subscribe and share your knowledge with others..BAM!! Glad you like the new videos too.
I haven’t even watched a minute of your video and I already had to like it because everything is so well explained with your graph and the functions next to each other. And what you just said about being opposites, not actually negatives.
You're welcome and thanks for subbing and seeking outside help to study with! Sounds like a great time to share my channel with your teacher for any other students who would benefit from some additional free after school math help...BAM!!!
HI I am an SAT Tutor, and some of my students ask me trig or Pre-calc questions which I haven't done in a while.I wanted to brush up, I have found your videos to be excellent. You explain things extremely well, these are great supplement for any student. Your students are lucky to have you as a teacher. Cheers
I used to tutor for SAT's a long time ago. There are some unique questions on that test that I do not work on everyday. I had a student ask me some questions recently from her SAT book and I felt like you do/did with Precalc, I need some brushing up!!! I am glad you find my lessons helpful. I will be sure to tell my "live" students that you said they need to appreciate me more:D:D:D haha Thanks!
Helped me so much... I think this is the only video that is +10min that I have watched with out wanting to take my eyeballs out. Made it easy and I love the different colors. Helps me see the different processes.

Wow Rob we are actually doing this right now in pre-calculus not lying. You are amazing my man. 30 minute video takes up a lot of bandwidth but it's worth it.
***** I do realize that now, but you understand my point though? Lots of data being transferred. It's better than streaming a dumb reality show or similar. I'd rather get an A in my math course than keep up with the kardashians or see who the last comic standing is.
TheVegetableAddict LOL...this is a proud moment for #ProfRobBob ! It's reassuring to hear that math is more important to some students than keeping up with the kardashians...NOW, if I could only get my subscriber count to be more important too I'd have that "M" I've been dreaming of:)
THANKS!!! ...and please keep sharing:D Here is a link to my websites list for Pre-Calc...you might find it easier to search:) www.profrobbob.com/pre-calculus
Professor RobBob, thank you for a smooth explanation of Even and Odd Functions. In Algebra Two/Precalculus, students should have a pattern recognition of Even and Odd functions. As I continue to review different types of Mathematics/Electrical Engineering classes, the same functions continues to appear everywhere.
***** I agree that absolute value functions can pose a challenge. If f(x)=|2x-7| and you try to check for even or odd you will have f(-x)=|-2x-7| which will hopefully show that the function is not even. I have students who struggle with algebra think that absolute value function will simply change all the signs inside the function or make ALL the negatives positive. I really like sketching the absolute value functions when possible to check for even or odd....this should be especially easy for linear absolute value functions like this one.
+ProfRobBob Do you have a video that shows how to solve a equation like this. f(x+c) f(x)=8x^3 +7x^2-5 I am having trouble figuring it out. The program they gave to help us with math doesn't make sense. It just goes from one thing to another without showing the individual steps. it just says this is the simplified version without explaining.
im age 30 from biology background and came to realize that maths is encroaching the field at advanced level..Fortunately i was good in math at highschool and i have Prof RobBob here to brush my basics back..To computational neuroscience ...........
I am always amazed by the comments I read on TH-cam. Math is a universal language and integral to so many fields of study. Sometimes I have never even heard the fields of study in which I am helping people achieve their goals! LOL Thank you for watching my math lessons and I am glad you are finding them helpful. I wish you great success in your career.

Hi Mr. Tarrou, this isn't exactly related to the video but I'm trying to figure out what I should be searching to understand this certain math problem I'm working on. I'm taking my College Algebra class online and I've been referring to your videos to help me understand these certain principles, but I'm stuck again. This problem I've been having difficulties is this: "Decide which of the polynomial functions in the list might have the graph below. (More than one answer may be possible.)" This problem then gives me a graph of a function that I am supposed to determine if it is even or odd (I believe it's odd if the right side of the function is above the x-axis and then the left side is below, is that correct?), what the degree is (is this how many times it crosses the x-axis? And then, how would this "degree" help me with the function? Would this be the amount of variables, or sets, that are in the function?), and then how would I know if the leading coefficient is positive or negative? Then I am to determine whether each "multiplicity of zero is even or odd" (I don't understand how to find the multiplicity from a graph, and how to determine if it's even or odd. In the function, wouldn't this be the exponent and the value of the exponent being an even or odd number?) and then find the functions that match up to my answers. I came here and watched this video thinking it would explain the evens and odds part of my function; you didn't explain this problem, but it helped me understand other problems I've been having. Do you have a video that explains this? If not, could you explain this to me? If you can't, what are these types of problems called so I can try to search for a website that will show how to solve this? Thank you! :)
It sounds like you need to watch these lessons on graphing higher order polynomials, vids 3 and 4 in this list www.profrobbob.com/pre-calculus/graphing-polynomials
Omg, my dad had that same shirt! Can't believe it took me 5 minutes into the video to notice. Now it will be hard to concentrate on what I need to learn for the rest of the videoxd I swear only cool people wear that shirt.
Odd functions are symmetric to the origin, meaning you can rotate the graph 180 degree about the origin and see the same graph. Symmetric to the line y=x is a reflection about that line. While at times it may seem like this is a symmetry, it will not hold for most graphs.
I have a question, on odd functions example #3. You have an odd exponent, and an exponent of 2. Wouldn't this function be neither? X^1 and inside the square root X^2? Just curious.....
When you are only working with polynomials it is easy to fall into the idea that odd functions have odd exponents and even functions have even exponents... or something like that. That is why I made this lesson with more complicated examples. You must analyze the relationship between the input and output values, not the exponents.
I do have a few cursive lessons when you need a break from math:) Please sub and share this free resource with everyone, especially your teachers...BAM!!!

Is it safe to say that “odd functions are symmetric to the line y=x”? Or is that not necessarily always the case.
Thank you
Odd functions are symmetric to the origin, meaning you can rotate the graph 180 degree about the origin and see the same graph. Symmetric to the line y=x is a reflection about that line. While at times it may seem like this is a symmetry, it will not hold for most graphs.

Is there a reason they're called 'even' and 'odd?'
I assume it is because formulas with even exponents represent even functions, and similarly with odd functions.
