Definition: Let f: A → R be a function defined on a set A containing the point c. We say that fis differentiable at c (or has a derivative f'(c) at c) if the limit below exist and is finite f'(c) = lim X→C f(x) = f(c) X-C We say that f is differentiable S≤ A iff f'(c) exists for all c E S. The function f': S → R is called the derivative of f on S. 1 a) f(x) = √, x > 0 b) f(x)=√x, x ≥ 0 Use the definition above to find the derivative of each function and determine the subset of its domain at which the derivative f' exists.
