Question

I found the answer to be 11, but it is incorrect.

Use the formula below to find the instantaneous rate of change of the function at the given x-value.
3x²+2x at x = 3
f(x)

Average and Instantaneous Rate of Change
The average rate of change of a function f between x and x + h is
f(x + h) − f(x). (Difference quotient gives the average rate of change.)
h
The instantaneous rate of change of a function f at the number x is
f(x + h) - f(x)
h
lim
h→0
X
(Taking the limit makes it instantaneous.)
