need help on the blank boxes...and I'm not sure that 1/9 is correct. helllppppppp

Evaluate lim f(x) and lim f(x) for the following function. Then give the horizontal asymptote off (if any) X-+00 X-+ -00 3x6 + 729 f(x) =- 2x2+ 17x4+ 64 3 x6 + 729 lim X- -00 2x2+ 1/7x4+ 64 (Type an exact answer, using radicals as needed.) 3x6 + 729 lim X-+00 2x2+ 17x4 + 64 (Type an exact answer, using radicals as needed.) Select the correct choice below, and, if necessary, fill in the answer box to complete your choice O A. The function has a horizontal asymptote at y = (Type an exact answer, using radicals as needed.) O B. The function has no horizontal asymptote
