Math Problem Statement

Write the absolute value inequality represented by this graph in terms of x.

Solution

The graph shows a number line with solid dots at -6 and 4, and a shaded region between them. This suggests that the solution includes all values of xx between -6 and 4, inclusive.

To express this as an absolute value inequality, we want to rewrite the interval 6x4-6 \leq x \leq 4 in terms of an absolute value. The midpoint between -6 and 4 is:

6+42=1\frac{-6 + 4}{2} = -1

This midpoint, -1, will be the center of our absolute value expression. The distance from -1 to either endpoint (4 or -6) is:

4(1)=5or6(1)=5|4 - (-1)| = 5 \quad \text{or} \quad |-6 - (-1)| = 5

Thus, the inequality can be written as:

x+15|x + 1| \leq 5

This is the absolute value inequality that represents the shaded region between -6 and 4.

Tip:

Always check the endpoints on the number line to determine whether to use strict inequality (<) or inclusive inequality (≤) based on whether the dots are open or closed.
