1. 1. Warm-Up 4/15 F 5

3. Rigor: You will learn how to find inverse functions algebraically and graphically. Relevance: You will be able to use functions to solve real world physics problems.

4. 1-7 Inverse Relations and Functions

6. Example 1: Graph each function and apply the horizontal line test to determine whether its inverse function exists.

7. One-to –one functions passes the horizontal line test and no y -value is matched with more than one x -value.

8. Example 2a: Determine whether f has an inverse function. If it does, find the inverse function and state restrictions on its domain.

9. Example 2b: Determine whether f has an inverse function. If it does, find the inverse function and state restrictions on its domain.

11. Example 3: Show that the functions are inverse functions. and
