Question

How do you find the average rate of change of `y=x^2+4` over [1,5]?

Answer 1

6

Explanation:

If y is differentiable over the interval, the formula for the average is

Average y'

= (Difference between end values of y) `/` (difference between end

values of x).

Here, it is `(y(5)-y(1))/(5-1)=(29-5)/4=6`
