Anyone feel like giving me a refresher of horizontal asymptotes?

Question

anonymous · Answer

sure.  if you have a rational function, vertical asymptotes are values for which the denominator is 0

http://www.purplemath.com/modules/asymtote2.htm OR http://www.tutorvista.com/math/horizontal-asymptote-definition A horizontal asymptote to any curve is defined as the line which touches the curve only at infinite points. The curve and the line never meet at finite points.

anonymous · Answer

horizontal ones go like this: if the degree of the denominator is bigger than the numerator it is 
y = 0

anonymous · Answer

if the degree of the numerator is bigger, there is no horizontal asymptotes

anonymous · Answer

and if the degrees are the same it is  y = ratio of leading coefficients

Thanks bunches. Nice clear, concise explanation!
