Answer:
-1
Explanation:
You want the average rate of change of the function shown in the graph between x=-1 and x=2.
Y-values
The y-value at x = -1 is 9.
The y-value at x = 2 is 6.
Rate of change
The graph changes by 6-9 = -3 units as x changes by 2 -(-1) = +3 units.
The average rate of change is ...
(change in y) / (change in x) = -3/3 = -1
The average rate of change from x = -1 to x = 3 is -1.
