Question: Let f(x) = 4+ -62 + 4x?. If h # 0, then the difference quotient can be simplified as f(= + h) - f(z) =

Let f(x) = 4+ -62 + 4x?. If h # 0, then the difference quotient can be simplified as f(= + h) - f(z) = Ah + Bx + C, h where A, B, and C are constants. (Note: It's possible for one or more of these constants to be 0.) Find the constants. A = B = and C = Use the simplified expression to find f'(x) = lim f(z + h) - f(z) h Finally, find each of the following. f'(1) =f(2) =] and f'(3) =
