  1. man you made it so clear, my teacher confused me every single time she did that thing :D
    this is a Aha moment THX :D

  2. The only edit I would make to this very clear presentation would be to include restrictions on the domain of logarithmic functions and trigonometric functions, since these figure so heavily in calculus. Otherwise, I send my muddle-headed precalculus/Trig students to this very video. For some reason, even though I present the exact same types of examples and info, some of my kids learn better from a video. I guess they think it’s entertaining. :-) Thanks for this clear presentation.

  3. Been watching many of your inverse videos + function videos for an upcoming test. I really want to thank you for the effort you put into every video it really helped me (and many others it seems) fully understand the material for school!

  4. hey your video was great but i still need help on a problem do you think i can give me my email so you can help me out? lol

  5. Dude this guy is a BOSS!!! way better explained then my teacher@ i love you bro your great!

  6. you thought me more about math in your 10min videos than my teachers have in 2 years

  7. I am interested to know how to record such a clear video as you did on the above video. Any recommendation on what gadgets that are required to be used to produce the video. I can be contacted  via email (just4anything@gmail.com) TQ

  8. I like how the domain is stated in America, it seems easier, in England we would say (or I would say based on what I was taught) something along these lines;
    x e R, x>0 and the range might be something like; f(x)>5 (where x e R means that x is the set of all real values)
