Answer

Explanation:

Step1: Recall increasing - function definition

A function (y = f(x)) is increasing on an interval if for any two points (x_1) and (x_2) in the interval with (x_1<x_2), we have (f(x_1)<f(x_2)). On a graph, the function is increasing when the graph moves up - ward as we move from left to right.

Step2: Analyze the given graph

Looking at the graph, we can see that the function is increasing on the intervals ((- 9,-6)) and ((-2,1)) and ((3,6)).

Answer:

((-9,-6),(-2,1),(3,6))
