Answer by robertb(5830)   (Show Source):
You can put this solution on YOUR website! Considering only the highest power for the numerator and denominator, the function is reduced to  . Letting x approach  , the limit of g(x) is 0. Hence the horizontal asymptote is y = 0.
The vertical asymptotes are exactly x = 2 and x = -2.

Find the equations of both vertical and horizontal asymptotes of the function.
Show work or Explain in words:
----
Vertical asymptotes where the denominator is zero: x = 2 and x = -2:
-----
Horizontal asymptote: y = 0x^2/x^2 = 0
As x goes to infinity y is determined by x/x^2.
