1 of the questions remains unanswered For each of the given functions f(x). find the derivative (f ) (c) at the given point c, first finding a = f (c). (See Theorem 7, page 156 of the Stewart Essential Calculus textbook) 1. f(z) = 61 + 81 ; c = -14 a = -1 (f 1) (c) = 78 2. f(x) = 12 - 12x + 41 on the interval [6, co); c =9 a = (f !)'(c) =]
