Answer

Explanation:

Step1: Recall decreasing - function definition

A function (y = f(x)) is decreasing 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 decreasing when the graph moves down - ward as we move from left to right.

Step2: Analyze the given graph

Looking at the graph of (y = f(x)), we observe the intervals where the graph is going down as (x) increases. We see that the function (y = f(x)) is decreasing on the intervals ((-1,2)) and ((5,\infty)).

Answer:

((-1,2)) and ((5,\infty))
