### Standard Course of Study

Objective 2.01

Use the composition and inverse of functions to model and solve problems; justify results.

### Lesson Objectives

What I will learn:

• Compute the inverse function for a given function

• Verify if two functions are inverses

FUNCTIONS?

INVERSE?

### Let’s put those concepts together.

Inverse Functions: Two functions that completely undo each other leaving only x.

### Examples: Find the inverse for the given function.
