1. The problem statement, all variables and given/known data Find (f(w) - f(x)) / (w-x) and (f(x+h) - f(x)) / (h) Simplify as much as possible. This section is a functions section, so I cannot take the derivative. 2. Relevant equations f(x) = 3x2-5 3. The attempt at a solution What is the w and the x? Also, what is the h? I have no idea where to begin. Thanks for your help.
