The vertical asymptote is x=0
No slant asymptote
The horizontal asymptote is y=2

Explanation:

Let f(x)=2-3/x^2

The domain of f(x) is RR-{0}

As you cannot divide by 0, x!=0

So, the vertical asymptote is x=0

As the degree of the numerator is = th the degree of the denominator, there is no slant asymptote.

lim_(x->+-oo)f(x)=im_(x->+-oo)(2-3/x^2)=2

The horizontal asymptote is y=2

graph{(y-(2-3/x^2))(y-2)=0 [-7.9, 7.9, -3.95, 3.95]}
