2. Review Homework

3. Agenda 1)Review HW 2)4.1: Inverse Functions and Relations Day 2 3)Practice Quiz

4. Learning Objective By the end of this period you will be able to: o Determine whether the function is one-to-one o Determine the inverse of a function and be able to graph the inverse

5. Warm-Up! 1. Simplify:

6. Whiteboard Find the inverse of f(x) = –1/2 x – 5.

7. One-to-One Function One-to-One Function: a.k.a 1-1 If f(x) is 1-1, then the inverse is also a function Graph passes vertical AND horizontal line test

8. Example 6

9. Whiteboard (a)Is the inverse of f(x) a function? (b) Find f -1 (x) Consider f(x) = x 2 – 4

10. Worksheet I am giving you until _______________ to finish the worksheet and turn it in to me.

11. Practice Quiz If you can do the practice quiz, then you can do the real quiz!!!! Unit 2 Quiz #1 Is the day you return from break!

12. Cool-Down Write a function on your whiteboard. Find someone that you haven’t worked with yet this year Swap whiteboards. Find f –1 (x) then state whether f –1 (x) is a function. Be ready to share out.
