\
The function is
.
(A)
\Domain :
\The function is
.
All possible values of
is the domain of the function.
Denominator of the function should not be zero
\

.
The domain of the function
is
.
\
(B)
\Intercepts :
\To find the
-intercepts, substitute
in the function.
.
Therefore the
-intercept is
.
To find the
-intercepts, substitute
in the function.

Therefore the
-intercept is
.
\
(C)
\Symmetry :
\Substitute
in the function.
.
Therefore the function
is neither odd nor even.
\
(D)
\Asymptotes :
\Horizontal asymptote :
\
Therefore the horizontal asymptote is
.
Vertical asymptote :
\Vertical asymptote appears when the function is not defined.
\The function is not defined at
.
Therefore the vertical asymptote is
.
\
(E)

\The function is
.
Differentiate on each side with respect to
.

.
Find critical points by equating
.

.
The function is undefined at
.
Critical points are
and
.
Test intervals are
,
and
.
