(3 points) Let f(x) = -6+ 8\\x. Then the expression f (x + h) - f(x) h can be written in the form A ( VBX + Ch ) + ( VIC ) 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 f(x + h) - f(x) h-0 h Finally, find each of the following: f' (1) = f' ( 2 ) =
