Let f(x) = -1 +5VE. Then the expression f(x th) - f(z) h can be written in the form A VBx + Ch) + (VI) 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 = C = Use your answer from above to find lim J ( + h) - f(x) h-+0 h lim f(Ith) - f(z) h-0 h Finally, find each of the following: f'(1) = f' (2) = f'(3) =
