Today

Objective: I CAN graph compound inequalities

Raise Your Hand if…

You are wearing a white tee shirt

ANDYou are wearing Black pants

Raise Your Hand if…

You are a female

ANDHave a binder for this class

Raise Your Hand if…

You are a male

ANDWearing sneakers

ORThe Pulaski bus to school

Define OR

OR: the word OR indicates that one statement, the other statement or both statements must be true

We call this the Union

Let’s look at some math

PICK ANY number for X and write it very large on a blank piece of paper

Now hold up your number if it is true?

AND

Now let’s Graph

Example #1 – Graph7x 2xAND

0 1 2 3 4 5 6 7 8

72 xWe can write this as:

Example #2 – Part B1x 4xor
