.
The -intercept is
.
Find the vertical asymptotes :
\Find the vertical asymptote by equating the denominator to zero.
\Thus, the function has vertical asymptote at .
Find the horizantal asymptote :
\To find horizontal asymptote, first find the degree of the numerator and degree of the denominator.
\Degree of the numerator is and degree of the denominator is
.
Here the degree of the numerator is greater than denominator, so the function will have oblique asymptote.
\Find oblique asymptote by long division.
\Here quotient is .
Oblique asymptote is .
Graph the function . \ \
