Question

use the graph of the function to estimate the intervals on which the function is increasing or decreasing.increasing $(-2.5, 1)$decreasing $(-)$

Explanation:

Step1: Identify decreasing intervals

A function decreases when its graph falls as $x$ increases. From the graph, the function falls when $x < -2.5$ and when $x > 1$.

Step2: Write interval notation

Combine the intervals using union notation: $(-\infty, -2.5) \cup (1, \infty)$

Answer:

Increasing: $(-2.5, 1)$
Decreasing: $(-\infty, -2.5) \cup (1, \infty)$
