Question

How do you find the average rate of change of `f(x)= 3x^2 - 2x` from 1 to 2?

Answer 1

`(f(2)-f(1))/(2-1) = ( ( 3(4)-2(2))-(3-2))/(1))`
=`(8-1)`
=`7`

Explanation:

average rate of change is the change in y over the change in x which is the slope formula of (y2-y1)/(x2-x1) byt instead of y we have f(x) which is the same thing.
