To determine the intervals where the function is increasing or decreasing, we need to observe where the graph goes upwards or downwards as we move from left to right.

Increasing Intervals:

The function is increasing when the graph moves upwards. From the graph:

1. The function increases from approximately $(-4, 2)$ to $(-2, 0)$.
2. It also increases from approximately $(0, -2)$ to $(2, 2)$.

So, the increasing intervals are:

• $(-4, -2)$
• $(0, 2)$

Decreasing Intervals:

The function is decreasing when the graph moves downwards. From the graph:

1. The function decreases from approximately $(-∞, -4)$.
2. It also decreases from approximately $(-2, 0)$ to $(0, -2)$.
3. Finally, it decreases from $(2, 2)$ to $(∞, ∞)$.

So, the decreasing intervals are:

• $(-∞, -4)$
• $(-2, 0)$
• $(2, ∞)$

Here are five related questions that might help expand on this topic:

1. How can you find intervals of increase and decrease using derivatives?
2. What are the critical points of a function, and how are they related to intervals of increase and decrease?
3. How do you determine concavity and inflection points from a graph?
4. What role do maxima and minima play in determining increasing and decreasing intervals?
5. How can you use the first derivative test to determine the nature of intervals?

Tip: To confirm the intervals where a function is increasing or decreasing, you can use the first derivative test.
