Question

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?

Answer 1

ok good

Answer 2

the denominator is \(2+h-2=h\) right?

Answer 3

the numerator you have to remember how to multiply out
\[(2+h)(2+h)\]

Answer 4

and then multiply the result by 3

Answer 5

clear or no?
