Homework Help: Difference Quotients

  1. Sep 16, 2006 #1
    This isn't a homework question, but I'm wondering if the following two equations can always be used interchangeably (thanks in advance):

    f(x)-f(c)/(x-c)

    and

    f(a+h)-f(a)/h

    yes, it's just substituting x for a+h and c for a, so then h = x-c.

    The problem I have with your post is that neither of the "equations" you give is an equation! (The lack of and "= " is a sure sign!)
