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 \ \
