-8 (1 point) Let f(x) = If h # 0, then the difference quotient can be simplified as 5 x + 5 f ( x + h) - f(x) A = h (Bx + Ch + 5)(Dx +5) where A, B, C, and D are constants. (Note: It's possible for one or more of these constants to be 0.) Find the constants. A = B = , C = , and D = Use your answer from above to find f (x) = lim f ( x + h) -f(x) h-0 h Finally, find each of the following: f' (1) = f' ( 2 ) = , and f' (3) =
