To determine over what intervals the function in the graph is negative, we need to observe where the curve lies below the x-axis (where $y < 0$).

From the graph:

• The function crosses the x-axis at points approximately $x = -3$ and $x = 0$.
• The function is negative (below the x-axis) between $x = -3$ and $x = 0$.

Thus, the correct interval where the function is negative is $(-3, 0)$.

Let me know if you need any further details or have any questions!

Here are 5 relative questions to further explore this topic:

1. What is the significance of the points where the function crosses the x-axis?
2. How do we determine whether a function is positive or negative in specific intervals?
3. How can we describe the behavior of the function in intervals where it does not cross the x-axis?
4. What role do critical points play in understanding a function's graph?
5. How can we analyze concavity based on the graph of a function?

Tip: Always check the behavior of a function at critical points and where it crosses the axes, as these points often give valuable information about the function's behavior across intervals.
