module 1 quiz score: 64.25/170 answered: 15/34 question 16 identify the open intervals on which the graph below is increasing and decreasing. increasing: decreasing: check answer

Answer

Explanation:

Step1: Recall increasing - decreasing rules

A function is increasing when the graph goes up from left - to - right and decreasing when it goes down from left - to - right.

Step2: Identify increasing intervals

Looking at the graph, it is going up on the intervals $(-5,-2)$ and $(1,5)$.

Step3: Identify decreasing intervals

The graph is going down on the interval $(-2,1)$.

Answer:

Increasing: $(-5,-2)\cup(1,5)$ Decreasing: $(-2,1)$
