Question

Given the function y = 4x + 3 do the following. Find its average rate of change: from x = 2 to x = 5

Answer 1

Answer: 4 is the average rate of change

Step-by-step explanation:

The equation to find the average rate of change is:

`(f(x_(2))-f(x_(1) ) )/(x_(2)-x_(1) )`

So f(2)= 11 and f(5)=23 then you plug these numbers in:

`(23-11)/(5-2)` =
`(12)/(3)` = 4
