Observe the graph :
\
intercepts :
The
intercept of the rational function are
.Since
is a
intercept,
is a factor of the numerator.
In the graph there appears another
intercept, Let the other intercept be
,which is the second
intercept,
is a factor of the numerator.
Vertical Asymptotes :
\The rational function has vertical asymptotes at
and
, therefore the zeros of the denominator should not be
and
.
Therefore the factors of the denominator are
and
.
Horizantal Asymptote :
\Because there is a horizontal asymptote at
, the degrees of the polynomials in the numerator and denominator are equal and the ratio of their leading coefficients is
.
Point :
\ Observe the graph the point is
.
The equation that satisfies all the above characterictics is
.
Subustiute the points
in the obtained equation
and solve for
. Here
.

Subustiute the value of
in the original equation
.

The rational function that represents the graph is
