Given these new options, let's analyze the intervals where the function is decreasing.

Looking at the graph:

1. The function decreases from $x = -3$ to $x = -0.5$.
2. The function then decreases again from $x = 3$ to $x = 5$.

Thus, the correct intervals where the function is decreasing match the second option:

• $x > -3$ and $x < -0.5$

Here are some related questions you might consider:

1. How can we use derivatives to confirm where a function is increasing or decreasing?
2. What are the critical points, and how do they relate to increasing/decreasing intervals?
3. Can you determine concavity from the graph of a function?
4. What is the significance of inflection points in the behavior of a function?
5. How can you identify points of inflection from the first derivative?

Tip: When determining where a function is decreasing, always consider the behavior of the function as it moves from left to right across the x-axis.
