Question #e9baa Calculus Limits Limits at Infinity and Horizontal Asymptotes 1 Answer Andrea S. Feb 21, 2017 #lim_(x->oo) ln(3x)-ln(2x) = ln (3/2)# Explanation: For any #a,b > 0# we have that: #ln(ax) -ln(bx)# is a constant. Using the properties of logarithms: #y(x) = ln(ax) - ln(bx) = ln ((ax)/(bx)) = ln (a/b)#. Answer link Related questions What kind of functions have horizontal asymptotes?
