a. Use limits to find the derivative function f for the following function f b. Evaluate f'(a) for the given values of a. X f ( x ) x+5 a - -3. 0 a. Identify the limit that should be evaluated in order to find the derivative function f', using h and not using f in your answer, f'(x) = lim h-0 Find the derivative function f'. f (x) = b. f(a) for a - - 3 is and f'(a) for a =0 is (Simplify your answers.)
