The average rate of change of the function on the interval [-2, 0] is -5/2, which means that the function's output decreases, on average, by 5/2 units for every 1 unit increase in the input value on that interval.
The average rate of change of the function on the interval [-2, 0] is -5/2.
Reasoning:
The average rate of change of a function over an interval is calculated by finding the difference in the function's output values at the interval's endpoints, and then dividing that difference by the interval's length.
In this case, the function's output at -2 is 3 and its output at 0 is -5. Therefore, the difference in its output values is -5 - 3 = -8.
The interval's length is |-2 - 0| = 2.
Therefore, the average rate of change is (-8) / 2 = -4.
