Please draw the graph also thanks

Page 4 of 4 5. (5 points) Consider the function f(x) = 723 - 3x2 + 8x + 4 a) Find the first and second derivatives of f (x): f' (2 ) = f" (2) = (b) Find the critical points of f, i.e., solve for the values x such that f' (x) = 0: (c) For what values of x is f'(x) > 0 and for what values of a is f'(x) 0 and for what values of x is f"(x)
