Q: Different quantifiers in the epsilon-delta definition of a limit.

BAS1CSLet $f(x)$ be a function defined on an interval containing $a$, except possibly not at $a$. Let $L\in\mathbb R$. Consider the statements: $\forall \epsilon>0,~\forall \delta>0,~0<|x−a|<\delta\implies|f(x)−L|<\epsilon$ $\exists \epsilon>0~~s.t.~~\exists\delta>0~~s.t.~~0<|x−a|<\delta\impli...

But maybe (examples-counterexamples) is a bit of a stretch for this one.
