Question

I need help!

Q: In two or more complete sentences, explain how to use ordered pairs of points in f(x) = 2x + 5 and g(x) = (x-5)/2 to determine if f(x) and g(x) are inverses of each other.

Answer 1

This should help :) http://www.coolmath.com/algebra/16-inverse-functions/05-how-to-find-the-inverse-of-a-function-01

Answer 2

Inverses do this: f(g(x)) = x
Put it through both and get back to where you started.
