Answer:
Average rate of change for the function
over the interval -1<x<1 is -1
Explanation:
We need to find average rate of change of f over the interval -1 < x < 1
The function given is:

The formula used to find average rate of change is:

We have, a = -1 and b = 1
Finding f(b) when b=1

Now, finding f(a), when a= -1

Now, putting values and finding average rate of change

So, average rate of change for the function
over the interval -1<x<1 is -1
