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 .
The rational function that represents the graph is .
