The rule is that if the degree of the numerator is greater than the degree of the denominator, then the x-axis is a horizontal asymptote. http://www.coolmath.com/precalculus-review-calculus-intro/precalculus-algebra/18-rational-functions-finding-horizontal-slant-asymptotes-01

so its y=2?

irishboy123 · Answer

i would do long division if i were you 

then see what happens as $x \to \pm \infty$

you can already guess something as you have $ \dfrac{O(x^2)}{O(x)}$ but the long div might make it clearer

Which part about the statement:  "the x axis is the horizontal asymptote" do you fail to understand?
