Question

How do you find the average rate of change of the function `f(x)=4 ·x^2 + 2 ·x−4` over the interval [3, 3.17]?

Answer 1

The average rate of change of a function `f` over an interval `[a,b]` is `(f(b)-f(a))/(b-a)`

Explanation:

So you need to do the arithmetic:

`(f(3.17)-f(3))/(3.17-3)`
