Find the vertical asymptote by equating the denominator to zero.
\



Apply zero product property.
\
and 
and
.
The vertical asymptotes are
and
.
\
Here the degree of the numerator is greater than denominator,so the function will have oblique asymptote.
\The degree of the numerator is
, it is greater than the degree of the denominator
.
The rational function
is improper.
