Homework Help: Alegbra

Posted by Jen on Friday, September 14, 2007 at 11:37pm.

I need to have some problems checked and I need help with one of them.

Determine which two functions are invereses of each other.

1. f(x)=5x, g(x)=x/5, h(x)=5/x
-I got that f(x) and g(x) are invereses

2. f(x)=x-2/2, g(x)=2x-2, h(x)=x+2/2
- I got that none are invereses.

5. f(x)=x^4 -3, g(x)=4th square root -3, h(x)=x^4 + 3
-I am not too sure how to find the inverse on this one.
