Question

what is the average rate of change of f over the interval -1 is less than or equal to x less than or equal to 1?

Answer 1

Without an illustration of f(x), or a function f(x), the rest of us can help you only in the most fundamental way.


Average rate of change of f(x) on the interval [-1,1] is as follows:
f(1) - f(-1) f(1)-f(-1)
ARC = ---------------- = --------------
1 - (-1) 2
