Answer:
[-6, 8]
Step-by-step explanation:
The range of a function is its vertical extent.
Here, the low point on the graph is (11, -6). The high point on the graph is (-6, 8). The graph is continuous between these points, so every value between a low of y=-6 and a high of y=8 is part of the range:
-6 ≤ y ≤ 8 . . . . . . . . [-6, 8] in interval notation
