Left Hand Derivative=Right Hand Derivative at point P for a function continuous at point P => function is continuous.

A function f(x) is said to be differentiable at a point x=a if the limit

exists and is equal for h->0+ and h->0- .

If you want to check differentiability in an interval then check if f'(x) is continuous for all x in that interval.

A functn is diffrntiabl at any p0in if its graph is c0ntinuous(no break) and there can b drawn only one tangent(no sharp turn) at that point..
