The rational function is
.
The function can be written as
.
Find the intercepts. \ \
\The function is
.
Change
to
.
.
To find
intercept, substitute
in the function.


intercepts are
and
.
To find
-intercept, substitute
in the function.

intercept is
.
\
Find the vertical asymptotes. \ \
\Find the vertical asymptotes by equating denominator to zero.
\

So the function has vertical asymptotes at
and
.
Find the horizantal asymptote. \ \
\To find horizontal asymptote, first find the degree of the numerator and degree of the denominator.
\Degree of the numerator
and degree of the denominator
.
The ratio of the leading coefficients of numerator and denominator are equal,and the degree of polynomial are equal
is horizontal asymptote.
So the function has horizontal asymptote at
.
The function is
.
Graph :
\Draw the coordinate plane.
\Graph the function
.
Find the domain. \ \
\The function is
.
The domain of a function is the set of all real numbers which makes the function mathematically correct.
\Denominator of the function should not be
.

Therefore the function is undefined at the real zero of the denominator
.
Thus the function is continuous for all real numbers except at
and
.
Therefore, domain of the function is
.
intercepts are
and
.
intercept is
.
The function has vertical asymptotes at
and
.
The function has horizontal asymptote at
.
Domain of the function is
.
Graph of the function
is \ \
