The average rate of change of the function over the interval is 2
Finding the average rate of change
From the question, we have the following parameters that can be used in our computation:
The graph
The interval is given as
From x = -3 to x = 3
The function is a quadratic function
This means that it does not have a constant average rate of change
So, we have
f(-3) = -8
f(3) = 4
Next, we have
Rate = (4 + 8)/(3 + 3)
Evaluate
Rate = 2
Hence, the rate is 2
