Suppose a call center projects the number of calls per hour to increase based on the function f (x) = 4x2+ 2x Using the definition of the derivative, f'(x) is equal to O lim 4h2 + 4hx + 2h h- 0 h 4h2 + 8hx + 2h h 4h2 + 4hx + 2h h lim 4h2 + 8hx + 2h h - 0 O lim 4h2 + 8hx + 2h h - 0 h O None of the other answers
