Review Homework

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

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

Warm-Up! 1. Simplify:

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

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

Example 6

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

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

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!

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.
