The function is
.
Domain :
\The function
.
The function
continuous for all the points except at
.
Thus, the domain of the function
is
.
Intercepts :
\
- intercept:
To find the
- intercept, substitute
in the function.

Thus, the function does not have
- intercept.
- intercept :
To find the
- intercept, substitute
in the function.

and 
Thus, the function has
- intercept at
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:
\To find vertical asymptote of the function
, equate denominator of the function to zero.

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:

Hence, there is no inflection points.
\But at
