Question

find the average rate of change in the simplest form of the function over the interval 4

Answer 1

Suppose the function is f.

Then the average rate

f(4) = 5

and f(5) = 10

Hence,

$\text{average rate of change =}\frac{f(5)-f(4)}{5-4}=\frac{10-5}{5-4}=\frac{5}{1}$

Hence the average rate of change over the interval 4
