The range of a graph refers to all possible $y$-values that the function can take. Looking at the graph you've provided, I can see that:

• The graph has its highest point around $y = 7$.
• The lowest point the graph reaches is approximately $y = -9$.

Therefore, the range of the function is from $y = -9$ to $y = 7$. In interval notation, this would be:

$[-9, 7]$

Let me know if you'd like further details, or if you have any other questions!

Here are 5 related questions for you:

1. What is the domain of the given graph?
2. How do you find the range of a graph when given a formula instead of a graph?
3. What is the difference between the range and the domain of a function?
4. Can a function have multiple ranges? Why or why not?
5. How do you determine if a function is continuous across its range?

Tip: The range of a function is determined by the $y$-coordinates of the graph, so always look for the highest and lowest points when examining a graph visually.
