Answer

Explanation:

Step1: Identify decreasing - part of graph

On a graph, a function $y = f(x)$ is decreasing when as $x$ increases, $y$ decreases.

Step2: Determine intervals

By observing the given graph, we see that the function is decreasing on the intervals $(- 10,-6)$ and $(2,6)$.

Answer:

$(-10,-6),(2,6)$
