1. The problem statement, all variables and given/known data Evaluate and simpliy [f(x+h) - f(x)]/h if f(x) = x^2 -2x 2. Relevant equations None 3. The attempt at a solution I just plugged in f(x), or x^2 - 2x for f(X+h) and f(x) and burned it down to h/h, or 1. That sounds too easy, though...want to know if it's correct.
