Use the four-step process to find f'(x), and then find f'(1), f'(2), and f'(3). f(x) = 11 +74x f' ( x ) = f' (1 ) = (Simplify your answer. Type an exact answer, using radicals as needed. Use integers or fractions for any numbers in the expression.) f' (2) =1 (Simplify your answer. Type an exact answer, using radicals as needed. Use integers or fractions for any numbers in the expression.) f'(3) = (Simplify your answer. Type an exact answer, using radicals as needed. Use integers or fractions for any numbers in the expression.)
