# Chapter 1 - Section 1.1 - Algebraic Expressions, Real Numbers, and Interval Notation - Exercise Set: 67

$\left\{x|-5 \le x \lt 2\right\}$ Refer to the attached image below for the graph.

#### Work Step by Step

A bracket on the left means that $-5$ is included in the set. A parenthesis on the right means that $2$ is not included in the set. Therefore, the set-builder form of the given interval is: $\left\{x|-5 \le x \lt 2\right\}$ To graph the interval, plot a hole (or hollow dot) at x=−2 and a solid dot at x=4, and then shade the region between them. (refer to the attached image in the answer part for the graph)
