if f(x) is differentiable on x_0 prove that ?? using the given i could say that lim [f(x+x_0) - f(x0)]/[x-x_0] exist

now let So Since Therefore Hence,
how did you know to pick those variables??
and why you didnt use the point x_0 that they presented there is another definition to limit is there a way to use this definition like you did before what variables to pick??

Does your problem require you to use that definition of ? Also what variables were you talking about in your other post?

A simple substitution will change your defition to Chiph's. Now what substitution is that?
if ill take x-x_0 =h
correct
