  • Thank u< u should post some videos on inverses

  • @619bluefish Do you mean inverse functions? If so, then go to my channel and search for "Inverse Functions". There is a video.

  • what do you do when their is no negative to factor out of the f of x when looking for negative f of x

  • @jeanniex0x0 We can always factor out a -1. For example: 2x-9 can be rewritten as -1(-2x+9).

  • what if it is in factored form with a degree of 5 or 6?

  • @fagg121213 It doesn't matter if the function is factored or not, or that it is even a polynomial function. What matters is that we need to find f(-x). If f(-x) simplifies down to f(x), then the function is even. If f(-x) simplifies down to -f(x), then the function is odd. If f(-x) simplifies to neither of those two things, then the function is neither even nor odd.

  • Awesome. I get it. You could just multiply by negative 1 to see if it's odd instead of factoring out a negative 1, right?

  • great thanks alot very clear and practical and understandable
