The derivative of a function of f at :1: is given by , : 1. f(m+h)f(w) f (3) I50 h provided the limit exists. Use the definition of the derivative to find the derivative of f (:3) = 5.1!:2 + 4:: + 3. Enter the fully simplified expression for f (m + h) f (as). Do not factor. Make sure there is a space between variables. f (ath) - f(2) = P Va a TT sin (a) III f' (20) =_
