Use the given information to sketch the graph of f. Domain: All real x, except x = - 6 and x = 6 f( - 9) = -2, f(0) = 0, f(9) = 2. f' (x) 0 on (-6, 6) f'' (x) 0 on (0, 6) and (6, co). Vertical asymptotes: x = - 6 and x =6, Horizontal asymptote. y = 0. Choose the correct graph below O A. O B. O c. Ay Ay
