The function is
and interval is
.
Find the intercepts :
\To find the
- intercept, substitute
in the function.

.
The
-intercepts are
and
.
To find the
-intercept, substitute
in the function.

.
The
- intercept is
.
Find the relative extrema:
\The function is
.
Apply derivative on each side with respect to
.


To find the critical numbers by equating
.


.
The solutions of
are
and
in the interval
.
Thus, the critical points occur at
and
.
If
, then
.
If
, then
.
The relative maximum is
.
The relative minimum is
.
Find the points of inflection :
\Consider
.
Apply derivative on each side with respect to
.



Find inflection points by equating
.


Apply zero product property.
\
and 
and 
There is no real solutions of
.
The solutions of
are
in the interval
.
If
, then
.
Thus, the inflection point is
.
Find the asymptotes :
\The function is
.
Vertical asymptote :
\The line
is a vertical asymptote if
.
.
.
The vertical asymptotes are
.
Horizontal asymptote :
\The line
is a horizontal asymptote if
.
.
.
Therefore, there is no horizontal asymptote for the function
.
