The function is
.
Domain:
\The function
.
The function
continuous for all the points except at
.
Thus, the domain of the function is
.
Intercepts:
\Find the
-intercept by substituting
:

Thus, the function does not have
- intercept.
Find the
-intercept by substituting

and
.
Thus,
-intercepts are
and
.
Symmetry :
\If
, then the function
is even function and it is symmetric about
-axis.
If
, then the function
is odd function and it is symmetric about origin.


Here
.
The function
is even function.
Thus, the function
is symmetric about
-axis.
Asymptotes:
\Vertical asymptote:
\Vertical asymptote exist when denominator is zero.
\Equate denominator to zero.
\The function
.

The vertical asymptote is
.
Horizontal asymptote:
\The line
is called a horizontal asymptote of the curve
if either
or 


Thus, the horizontal asymptote is

Determination of extrema :
\The function has a local minimum as the
is changing its sign from negative to positive at

As the function is not defined
, the function
has no local minimum or maximum.
Determination of inflection point:
