Proving continuity of a differentiable function.

Hi
 
I have been given a function f:(a,b)→R, which is differentiable on (a,b). How do I use this information to prove that f is also continuous on (a,b)?
 
Thanks.

I am aware of this, but how do I prove it?

it's a tautology. A proof can be verbal, and I offered those words as proof.
