The range of a graph refers to the set of all possible output values (y-values) of the function.

From the given graph:

1. The highest point (maximum y-value) appears to be at approximately $y = 2$.
2. The lowest point (minimum y-value) appears to be at approximately $y = -8$.

Therefore, the range of the graph is: $[-8, 2]$

This indicates that the function's y-values span from -8 to 2, inclusive.

Tip: To confirm range, check extreme values of y on the graph (highest and lowest points).
