## Homework Statement

Evaluate the difference quotient of:

f(1+h)-f(1) / h

if f(x)=x

^{3}

and simplify your answer.

## Homework Equations

## The Attempt at a Solution

I took the derivative of x

^{3}to be 3x

^{2}and solved for when x=1 (given from the difference quotient) and got 3, but when I enter the value it's marked incorrect. Not sure what I'm doing wrong, unless I just interpreted the question the wrong way.
