From the graph, we can observe the behavior of the function based on where the slope is positive (increasing) and where it is negative (decreasing).

Increasing Intervals:

The function is increasing where the slope of the graph is positive (upward). This occurs between:

1. $(-\infty, -2)$
2. $(0, 2)$

Decreasing Intervals:

The function is decreasing where the slope of the graph is negative (downward). This occurs between:

1. $(-2, 0)$
2. $(2, \infty)$

To summarize:

• Increasing on: $(-\infty, -2) \cup (0, 2)$
• Decreasing on: $(-2, 0) \cup (2, \infty)$
