The solution set of which of the following inequalities is shown on the number line above?
x2 ≥ 36
x2 ≤ 36
|x| ≤ 36
Text Solution:
On the number line, we see that the shaded region is between -6 and 6, and both -6 and 6 are included. Thus, this region represents the inequality . Or, written another way, this inequality is . Using the patterns we observed in this section, we know this is the solution set of the inequality .
