3

Which of the inequalities below corresponds to the following graph?

Question illustration
A
|−2x − 4| = 6
B
|x − 2| > 4
C
|2x + 4| < 6
D
|x + 2| ≤ 4
4

The solution set x ≤ 2 or x ≥ 4 is consistent with an equation of the form

A
|ax + b| ≤c, where c is greater than zero.
B
|ax + b| ≥ c, where c is greater than zero.
C
|ax + b| = c, where c is less than zero.
D
|−ax + b| ≤ c, where c is less than zero.
