Finding the Average Rate of Change

[AnyColour]

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!

Average rate of change of f(x) between x[sub:xhmewc0o]1[/sub:xhmewc0o] and x[sub:xhmewc0o]2[/sub:xhmewc0o] is = [f(x[sub:xhmewc0o]2[/sub:xhmewc0o]) - f(x[sub:xhmewc0o]1[/sub:xhmewc0o])] / [x[sub:xhmewc0o]2[/sub:xhmewc0o] - x[sub:xhmewc0o]1[/sub:xhmewc0o]]
