Answer:

Look at the coefficients on the variables with the greatest exponents for both the numerator and denominator ...

Explanation:

Numerator : highest exponent is 1 #(1x^1)#and the coefficient is also 1.

Denominator : highest exponent is 3 #(1x^3)# and the coefficient is 1

So we have #(1x)/(1x^3)#. As #xrarroo#, this rational function goes to zero .

Therefore, horizontal asymptote is #y=0#

hope that helped
