The rational function is .
Find the intercepts :
\The function is .
Change to
.
.
Find the intercepts.
\To find intercept, equate numerator to
.
\
intercepts are
and
.
Find the intercept by substituting
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
.
Since the degree of the numerator is equal to the degree of the denominator, horizontal asymptote is the ratio of leading coefficient of numerator and denominator.
\Leading coefficient of numerator , leading coefficient of denominator
.
is horizontal asymptote.
So the function has horizontal asymptote at .
\
Graph :
\The graph of the function .
\
Find the domain :
\The domain of a function is the set of all real numbers which makes the function mathematically correct.
\Denominator of a function should not be .
Thus, the function is continuous for all real numbers except .
Therefore, domain .
Domain is .
The function has vertical asymptotes at and
.
The function has horizontal asymptote at .
The graph of the function is
