How do you find #lim sqrt(x+2)/(sqrt(3x+1)# as #x->oo#? Calculus Limits Limits at Infinity and Horizontal Asymptotes 1 Answer Eddie Mar 2, 2017 # = 1/sqrt(3)# Explanation: #lim_(x to oo) lim sqrt(x+2)/(sqrt(3x+1)# #= lim_(x to oo) lim (sqrt(x) (sqrt(1+2/(sqrt x))))/(sqrt x (sqrt(3+1/(sqrt x)))# #= lim_(x to oo) lim ( (sqrt(1+2/(sqrt x))))/( (sqrt(3+1/(sqrt x)))# # = 1/sqrt(3)# Answer link Related questions What kind of functions have horizontal asymptotes?
