Which of the following must be true?

I. f is continuous at x=2.

II. F is differentiable at x=2.

III. The derivative of f is continuous at x=2.

I know (I) is true because it can be differentiated

I know that (II) is ture to because the derivative was found so it can be differentiable.

I don't know if III is true because the it doesn't tell me the limit of f'(x)

are these correct?
