# Thread: [SOLVED] Finding the Average Rate of Change

1. ## [SOLVED] Finding the Average Rate of Change

Hi there. I'm stuck on this one.

Find the average rate of change of f(x)= -3x^2+4:
a) From 0 to 2
b) From 4 to 6
c) From 2 to 5

Thanks!

2. It's just a formula. Is is also colled the "slope" in algebra 1.

$
\frac{f(x_{2})-f(x_{1})}{x_{2}-x_{1}}
$

Plug and chug.
