Theorems about convex functions often look like the following:
Let f: S->R where S is a convex set.
Suppose f is a convex function...
So here are my questions:
1) For a convex function, why do we always need the domain to be convex set in the first place?
2) Can a convex function be discontinuous?
Thanks for any inputs.
