Answer:
A -4 ≤ x ≤ -2
Step-by-step explanation:
The graph is constant where there is a flat, horizontal line. The graph is flat in the interval -4 ≤ x ≤ -2. This is where the graph will be constant. In all of the other parts of the graph, the y-values are changing. Since the line is flat, the y-value doesn't change.
