1. Monday Turn in Homework to basket! Solve and graph each of these inequality solutions in your notebook

2. Unit 1 Interval Notation vs Inequality Notation

3. Objectives I can write a solution in Inequality Notation I can write a solution in Interval Notation

4. These are all in Inequality Notation We are going to change them to INTERVAL NOTATION

5. Symbols for Interval Notation? [ ] means “included” (equal to) ( ) means “not included” HIGHLIGHT THIS IN YOUR NOTEBOOK! Like a closed dot,, > < Like an open dot,, > <
