Consider a linear function f(x) = mx + b (where the slope is not 0).
What is f-1(x)?
Use this formula to find the inverse of
h(x) = 2x - 9.

Answers:

and

See note below

====================================================

Explanation:

First we replace f(x) with y. Then we swap x and y. Afterward, solve for y to determine the inverse function. The m value cannot be zero to avoid dividing by zero.

-----------------

For the formula h(x) = 2x-9, we see that m = 2 and b = -9

So the inverse for h(x) would be:

Note: The function is the same as saying or , so it will depend on what format your teacher wants.
