To determine the range of the graph, we need to observe the values that the function takes along the y-axis.

From the image:

• The highest point (maximum) on the graph appears to be around $y = 9$.
• The lowest point (minimum) on the graph seems to be around $y = -10$.

Therefore, the range of the function, which describes the set of all possible $y$-values that the graph can attain, is: $[-10, 9]$

This means the graph covers all $y$-values between $-10$ and $9$, inclusive.

Do you have any questions or would you like further details?

Relative Questions:

1. How is the domain of a function related to its range?
2. What is the significance of the maximum and minimum points on a graph?
3. How can you tell if a graph has any asymptotes by looking at it?
4. What are some ways to calculate the range algebraically if the equation is known?
5. How does the range of a quadratic function compare to this graph's range?

Tip:

When determining the range, always scan the graph from the lowest point to the highest point on the y-axis to ensure no values are missed.
