Evaluate lim f(x) and lim f(x) for the following function. Use co or - co where appropriate. Then give the horizontal asymptote(s) of f (if any). X -+ 00 X - 00 x3 +4 f ( x ) = 2 x + 1 16 *0 + 1 Evaluate lim f(x). Select the correct choice below and, if necessary, fill in the answer box to complete your choice. X -+ 00 OA.X lim f(x) = (Simplify your answer.) X - 00 O B. The limit does not exist and is neither co nor - co. Evaluate lim f(x). Select the correct choice below and, if necessary, fill in the answer box to complete your choice. X - - 00 O A. lim f(x) = (Simplify your answer.) X - - 00 O B. The limit does not exist and is neither co nor - co. Identify the horizontal asymptote(s). Select the correct choice below and, if necessary, fill in the answer box to complete your choice. O A. The horizontal asymptote(s) is/are y =. (Simplify your answer. Use a comma to separate answers as needed.) O B. There is no horizontal asymptote
