What is the limit of # (x^3 - 2x +3) / (5-2x^2)# as x goes to infinity? Calculus Limits Limits at Infinity and Horizontal Asymptotes 1 Answer Jim H Oct 23, 2015 #lim_(xrarroo) (x^3 - 2x +3) / (5-2x^2) = -oo# Explanation: #lim_(xrarroo) (x^3 - 2x +3) / (5-2x^2)# has indeterminate form #oo/oo#. For all #x !=0# we get #(x^3 - 2x +3) / (5-2x^2)= (x^2(x-2/x+3/x^2))/(x^2(5/x^2-2))# So #lim_(xrarroo) (x^3 - 2x +3) / (5-2x^2) =lim_(xrarroo) (x-2/x+3/x^2)/(5/x^2-2) =oo/-2 = -oo# Answer link Related questions What kind of functions have horizontal asymptotes?
