Different quotient (and similar) practice problems 1. For each of the following functions, simplify the expression f (x + h) - f(x) h as far as possible. In particular, you should be able to rewrite each expression without an h in the denominator. (a) f(x) = 2x +5 ( b) f ( ) = 3 - 2 (c) f(x) =12 (d) f(x) = 2x2 - x (e) f(x) = =22+3x-4 (f) f (I ) = VI (g) f(x) = Vx2 -1 For f t
