I'm having trouble getting started with a calculus problem, can anyone help me?

The limit represents the derivative of a function taken at a point. What function? What point? What is the limit?

I need help getting started with this problem...

Well as the point is

I get

What methods for taking limits have you been taught? - Aug 30th 2010, 04:17 PMRU2010
Sorry, I didn't really explain this problem well. I knew the answer to the acutal limit, and the point, but I'm having trouble figuring out what function this represents the derivative taken at a point of.

If this limit represents the numerical derivative of 1/4 taken at x=4, what would the original function that I'm taking the derivative of be?
