How do you find the limit #lim (3^(x+1)-2^(x+4))/(3^(x-2)+2^(x-1)+6)# as #x->oo#? Calculus Limits Infinite Limits and Vertical Asymptotes 1 Answer Cesareo R. Oct 18, 2017 #3# Explanation: #lim_(x->oo) (3^(x+1)-2^(x+4))/(3^(x-2)+2^(x-1)+6) = lim_(x->oo)(3^-1-2^4*(2/3)^x)/(3^-2+2^-1(2/3)^x+6/3^x) = 3# Answer link Related questions How do you show that a function has a vertical asymptote?
