Q. 16 - Precalculus Enhanced with Graphing Utilities

Question

In Problems 11–20, use the graph of the function f given.   

List the interval(s) on which f is decreasing.

Step-by-Step Solution

Answer

Decreasing intervals are :

$(-\infty ,-8); (-2,0); (2,5)$

Step 1: Given Information

use the graph of the function f given.    

Step 2: Decreasing intervals

Decreasing intervals are the intervals where the graph goes down . we look at the x values where the graph goes decreasing. 

Decreasing intervals are 

$(-\infty ,-8); (-2,0); (2,5)$
