Inverse Functions
Finding Inverse Functions
Remember that an inverse function reverses the inputs and outputs. When we graph functions, we always represent the incoming number as x and the outgoing number as y. To find the inverse function switch the x and y values and then solve for y.
Example: Find the inverse function of 
.
Step 1. Replace f(x) with y in the equation describing the function.
Step 2. Interchange x and y. In other words, replace every x with a y and vice versa.
