The rational function is .
Find the intercepts.
\The function is .
Change to
.
.
To find intercept, substitute
in the function.
intercept is
.
To find -intercept, substitute
in the function.
There is no intercept because
is defined for
.
No -intercept.
Find the vertical asymptotes.
\Find the vertical asymptotes by equating denominator to zero.
\The function has vertical asymptotes at .
Find the horizantal asymptotes.
\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 denominator is greater than the degree of the numerator, horizontal asymptote .
is horizontal asymptote.
The function has horizontal asymptote is .
Graph :
\Graph the rational function :
Find the domain.
\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 .
Therefore, domain of the function is .
intercept is
.
No -intercept.
The function has vertical asymptotes at .
The function has horizontal asymptote is .
Domain of the function is .
