f(x) =x^2+2/x^2+x-2

OR ?

The second definition is assumed in this work.

First, here is the graph, simply applying the graphing code for the site:

Factorize numerator and denominator completely, at least for Real number purposes.

No hole since no factor is common between numerator and denominator.

Undefined for x=1 and x=-2, so this causes vertical asymptotes.

Degree of numerator and denominator both EVEN and EQUAL, so as x tends unbounded in either direction, f approaches 1. Horizontal asymptote y=1.

Try polynomial long division. You will find 1 plus some rational expression, consistant with what is found as the horizontal asymptote. NO oblique asymptote!
