Answer:
-1
Step-by-step explanation:
The graph goes through the points (-1, 1) and (1, -1). The average rate of change is the slope of the line through those points. It can be calculated using the slope formula. Alternatively, you can recognize that the line will have a "rise" of -1 for each "run" of 1, so rise/run = -1/1 = -1.
__
Using the slope formula, we have ...
m = (y2 -y1)/(x2 -x1)
m = (-1 -1)/(1 -(-1)) = -2/2 = -1
The average rate of change on the interval is -1.
