Hey. I am quite confused by continuity and derivatives. Both are finding the limits of a particular function as x approaches a. Then why is it that a graph that is continuous cannot be differentiable? If it is continuous, it means that the limit exists and so, it should be differentiable right?

If p is three, does that mean q has to be three as well?
The limits used in the definitions of continuity and differentiability of a function f are different limits.

For example, a function with a "point" (f(x)=x has a point at x=0) can be continuous but not differentiable since the derivative is different on either side of the point.
