Answer:
-0.125
Step-by-step explanation:
The points on the graph referenced by the problem statement are ...
(x, y) = (-1, -0.25)
(x, y) = (1, -0.50)
The average rate of change between the two points is ...
(∆y)/(∆x) = (-0.50 -(-0.25))/(1 -(-1)) = -0.25/2 = -0.125
The average rate of change of the function shown on the interval [-1, 1] is -0.125.
