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

Unit 1 Interval Notation vs Inequality Notation

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

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

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

Infinity??? We ALWAYS use ( ) with infinity!!! All negative numbers All positive numbers HIGHLIGHT THIS IN YOUR NOTEBOOK!

Symbols INQ: Inequality Notation INT: Interval Notation

What would be different for these?

What would we do if the solution was ALL REAL NUMBERS?

PRACTICE Graph it on a number line. Change it to interval notation
