Derivative of a function

Problem 11. (1 point) The Derivative as a Function. Determine the value or values of :1: for which the tangent to f is horizontal by first finding the derivative of f with respect to 1: then solving f'(:z:) = 0 for 9:. PART 1. f(9') = $2 xlO f'(aa) = ' (xA2-20x)/(x-10)'\\2 l h _ NOTE: for this problem, you should use the denition of derivative, f '(x) = gin?) W or the equivalent form f '(93) = 11in M _, z z Z 12 PART 2. The tangent to the curve is horizontal at: :] NOTE: Type answer in form :5 = a Separate multiple answers with a comma, such as m = 17 :r: = 1 Note: You can earn partial credit on this problem.
