The vertical asymptote is x=2x=2
The horizontal asymptote is y=0y=0

Explanation:

As you cannot divide by 00, you have a vertical asymptote x=2x=2
There is no slant asymptote as the degree of the numerator is smaller than the degree of the denominator.
lim_(n rarr -oo )f(x)=lim_(narr-oo)4/x^3=0^-

lim_(n rarr +oo )f(x)=lim_(narr+oo)4/x^3=0^+

So there is a horizontal asymptote y=0
