Question

Write an absolute value inequality for each graph

55.

Step-by-Step Solution

Answer

Absolute value inequality is $\left|x\right|<2.8$

Step 1 - Definition of absolute value inequality

For real numbers $a\text{ and }b$ with $b>0$

Absolute value inequality is $\left|a\right|<b$ when $-b<a\text{ and }a<b$, and

Absolute value inequality is $\left|a\right|>b$ when $a<-b\text{ or }a>b$

Step 2 - Observation from image

From image, solution is all real less than $2.8$ and greater than $-2.8$

Step 3 - Write absolute value inequality

Let the real number be x

As $x>-2.8\text{ and }x<2.8$ so from definition, absolute value inequality is 

$\left|x\right|<2.8$
