Chapter 1: Q13. (page 44)

Solve each inequality. Graph the solution set on a number line.
$|w| 鈮� - 2$ .

Short Answer

Expert verified

The solution of the given inequality is $w > - 2 o r w < 2$ .

Step by step solution

-Define absolute inequality and write the inequality

A For all real numbers a, b and $b > 0$ ; it is true that if $|a| 鈮� b$ then $a > b$ or $a < - b$ . The inequality is $|w| 鈮� - 2$ .

– Apply the definition of an absolute compound inequality

Use the definition of absolute value inequality and write the compound inequality with word or as follows:

$\begin{array}{l} | w | 鈮� - 2 \\ w > - 2 o r w < - (- 2) \\ w > - 2 o r w < 2 \end{array}$

– Graph of the solution set

The graph for the inequalities $w > - 2 o r w < 2$ is as shown below
