Best ResponseYou've already chosen the best response.0That is just a complicated way of asking you: "What is the derivative of x^3.25 ?"

Best ResponseYou've already chosen the best response.0If you are allowed to "use your knowledge of the derivative", you could say that by definition the derivative of a function (here your function is x^3.25) is the limit as h approaches 0 of f(x + h)  f(x). Therefore, this limit equals the derivative of x^3.25 which is (and you know how to do the derivative, right?)

Best ResponseYou've already chosen the best response.0so whats the main purpose of these kinds of questions? for ex: what if it was a square root problem... do we find only the deriative of the f(x+h) an thats our answer?

Best ResponseYou've already chosen the best response.0find the derivative of f(x)...forget about the h. I think your prof just want's you to see how easy it is to do limits in that form now that you can do derivatives. Or maybe he / she wants to reinforce how derivatives relate to limits.
