(1 point) Let f(x) = 3x + 4. If h # 0, then the difference quotient can be simplified as f ( x + h) - f(x) A = h VBx + Ch+ vx 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 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)
