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.

Answer 1

Answer 2

In inverse functions, you switch the x and y values.

Answer 3

For example:

2x + 5

2(1) + 5

2 + 5

7

So we have (1, 7). The inverse function would be (7, 1)
