The image shows a graph of a function, and the question asks for the range of the function represented in the graph. Let's analyze the graph:

• The graph seems to be a cubic function with two turning points, and it reaches its minimum and maximum at $y = -3$ and $y = 3$ respectively.
• The question offers four choices for the range:
  1. $y \geq 0$
  2. $y \geq -4$
  3. All real numbers
  4. $-3 \leq y \leq 3$

Based on the visual inspection, the function has values ranging from $y = -3$ to $y = 3$. Therefore, the correct range of the function is $-3 \leq y \leq 3$, which corresponds to choice D.

Here are 5 related questions:

1. What is the domain of the given function?
2. How do we determine the range of a function graphically?
3. Can a cubic function have a range of all real numbers?
4. How does the shape of the graph help in identifying critical points?
5. How do we calculate turning points for a cubic function?

Tip: The range of a function is the set of all possible output values (y-values) that the function can take. You can find it by looking at the vertical extent of the graph.
