When is a function differentiable?

Suggested Prerequesites: The definition of the derivative, Continuity


A function is differentiable when the definition of differention can be applied in a meaningful manner to it.

When would this definition not apply? It would not apply when the limit does not exist. Then, we want to look at the conditions for the limits to exist.
