Answer: [tex]-4 < x < -1[/tex] and [tex]x > 2[/tex]
Explanation:
The graph is increasing when the curve moves uphill as you move to the right. In other words, as x increases, y increases.
The first portion where the graph increases is from x = -4 to x = -1. In the span of -4 < x < -1 is when the graph goes uphill as shown by the red portion below. The blue portion is the second increasing piece that goes on forever upward, and this happens when x > 2.
