To find:

The intervals where the function is increasing and decreasing.

Solution:

A function is increasing if the function increases as the value of x increases.

A function is decreasing if the function decreases as the value of x increases.

From the given graph it is clear that the graph is decreasing for , then the graph increasing for after that the function again start decreasing for .

Function Increasing over:

Function decreasing over: .

Therefore, the function is increasing over the interval and the function is decreasing over the interval .
