Question

use the graph of the function to estimate the intervals on which the function is increasing or decreasing. (enter your answers using interval notation.) increasing decreasing

Explanation:

Step1: Identify increasing intervals

Observe where the graph rises as x - values increase. The graph rises from $x=-1$ to $x = 1$ and from $x = 4$ to positive - infinity.

Step2: Identify decreasing intervals

Observe where the graph falls as x - values increase. The graph falls from negative - infinity to $x=-1$ and from $x = 1$ to $x = 4$.

Answer:

Increasing: $(-1,1)\cup(4,\infty)$
Decreasing: $(-\infty,-1)\cup(1,4)$
