1. 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

2. 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.

3. 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
