Evaluate lim f(x) and lim f(x) for the following function. Use co or - co where appropriate. Then give the X -00 X - - 00 horizontal asymptote(s) of f (if any). 2 x + 6 f ( x ) = 3x3 + 136x6 +4 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. Evaluate lim f(x). Select the correct choice below and, if necessary, fill in the answer box to complete your choice. X- -00 lim f(x ) = (Simplify your answer.) O A. - x- - 90 O B. The limit does not exist and is neither co nor - co. Identify the horizontal asymptote(s).
