Determine the average rate of change of the function between the given values of the variable.
f(x) = 3x^2; x=2, x= 2+h
Can anyone show me how it is worked out?
so far i have up to:
3(2+h)(2+h) - 12 / 2+h - 2
How do I simplify?

ok good

anonymous · Answer

the denominator is $2+h-2=h$ right?

anonymous · Answer

the numerator you have to remember how to multiply out 
$$(2+h)(2+h)$$

anonymous · Answer

and then multiply the result by 3

anonymous · Answer

clear or no?
