→Basically, the question is asking, "At what point is the line on the graph decreasing?"
→Looking at the graph, you can see that when x = -4, that's when the line on the graph starts to decrease. The line continues to decrease, until it reaches the point where x = 2.
<u>This makes the correct answer "B. -4 ≤ x ≤ 2."</u>
