Continuous functions and derivatives?

A function has a derivative in all of the domain. Is the derivative a continuous function?

Update:

Thx for the help but I what meant is if f' continuous? not f.

    In order for a function to be differentiable (you can take the derivative of it), it must be continuous. So if the function has a derivative over its whole domain, it is always continuous.

    Hmm. lacking derivatives at some particular factor, particular. lacking any derivatives in any respect? i do no longer think of so. y = (absolute value of x) is a V-shaped graph that would desire to lack a spinoff at x=0, because of the fact the slope may be -a million coming from the left and +a million coming from the appropriate.
