Question

the graph if this function is increasing at which interval?
-1.5, 2
0, 2
2, ∞
-∞, -1.5

Explanation:

A function's graph is increasing when it rises from left to right. Observing the given graph, it increases between the local minimum (around x=-1.5) and local maximum (around x=2). Thus, the interval is [-1.5, 2].

Answer:

[-1.5, 2]
