Help on these problems

[Scoota]

Please forgive me if I am being exceptionally demanding but I have recently taken on the course of precalculus and considering how new I am, I am finding it hard and confusing so I might need some help. Anyway, could you please help me on the following problems:

Anyone, there to help me?

By "help me", you mean "Do my homework for me so I won't run the terrible risk of actually learning something"!
The problem appears to be that you have not learned this subject!
For example, problem 102 asks you for [math]f(f^{-1}(9))[/math] and specifically says that "f has an inverse". Do you know what that MEANS?

Prolem 107 asks for the inverse function to [math= -2- x^2[/math].
If [math]y= -2- x^2[/math] then the inverse satisfies [math]x= -2- y^2[/math].
Solve that for y to get the inverse function.

All of these problems involve the inverse function but you don't appear to know what THAT is!
