One vertical asymptote x=0 and one oblique asymptote y=x

Explanation:

In h(x)=(x^2-4)/x,

vertical asymptotes are obtained by putting denominator equal to zero.

Hence x=0 is the only vertical asymptote.

As the highest degree of numerator is x^2 and of denominator x are not equal, there is no horizontal asymptote. But it is just one degree higher than that of denominator,

hence we have one oblique asymptote given by y=x^2/x=x
