Answer

The solution set is {x|1≤x≤3} or [1,3]. To graph you would place a bracket on 1 and 3 on the number line and connect them by a line.

Work Step by Step

|x-2|≤1 In order to solve, we set the equation up like this: -1≤x-2≤1 -1+2≤x-2+2≤1+2 1≤x≤3 The solution set is {x|1≤x≤3} or [1,3]. To graph you would place a bracket on 1 and 3 on the number line and connect them by a line.
