Presentation transcript:

Interval and Inequality Notation interval: a group of numbers defined by an inequality defines the interval of all numbers starting at but not including 3, and larger. defines the interval of all numbers starting at 2 and stopping at 4, including 2 but not 4

Interval and Inequality Notation closed interval: an interval that includes both endpoints. open interval: an interval that includes neither endpoint. half-open interval: an interval that includes either one or the other endpoint, but not both.

Interval and Inequality Notation bounded interval: an interval with two endpoints. unbounded interval: an interval with only one real number endpoint. Inequality notation => Interval notation

Ex 1: Describe and graph the interval: ( ] -2 4
