Inverse Functions and Restricted Domains
I'm taking an online Calculus course and it's been a while since I've done calculus. I'm getting really frustrated because I can't remember how to do some of this stuff. Please give me some help, and explain the answers, thanks a lot.

Where specifically do you run into problems?

This appears to be a graded assignment.
It is against forum policy to help in that case.

On problem 3 when I take the inverse of f(x) I keep getting x+1=y(y^2+3), I'm not really sure what i'm supposed to do next.

I understand that but I need help on these assignments badly and I can't afford a tutor, if anybody is willing to just help me along with the problems it'd be great, I'm not asking for anybody to do them for me.

you do not need to find the inverse function to answer the question, just follow the given directions.

here's a hint ... if f(0) = 1, then g(1) = ?
