Question

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. PLEASE EXPLAIN!

Answer 1

You would do f(1)=2(1)=5, and g(1)=1-5/2. Then, you would compare the answers of both equations, after doing x=1, x=2, and x=3.
