Directions Consider the following function f x at a 8 Part 1 Difference Quotient If h 0 then the difference quotient can be simplified into the form f 8 h f 8 8 h where A and B are constants Find these constants A and B Note It s possible for one or more of these constants to be 0 f x x 7 f 9 1 VA h B Part 2 Derivative Use the simplified expression from Part 1 to then calculate the derivative f 8 f 8 lim h 0 That is 1 A h B f 8 h f 8 h
