Chapter 3 - Solving Inequalities - 3-6 Compound Inequalities - Practice and Problem-Solving Exercises: 37

Answer

$3\leq x\lt6$

Work Step by Step

A single line on the graph with two endpoints means that x is between the two endpoints. The solid circle at the left endpoint means 3 is part of the solution set, so the inequality operator includes "or equal to." The open circle at the right endpoint means 6 is not part of the solution set, so the inequality operator does not include "or equal to."
