# Appendix D - Exercise Set: 45

$x∈[-4;4]$ To graph the solution set, put two square brackets such that they enclose the interval $[-4;4]$.

#### Work Step by Step

The absolute value of x is inferior or equal to 4. Therefore, the value of x cannot be larger than 4, neither smaller than -4. The solution set contains all numbers whose distance from 0 is less than or equal to 4.
