The function is \"\".

\

Domain:

\

The function \"\".

\

The function \"\" continuous for all the points except at \"\".

\

Thus, the domain of the function is \"\".

\

Intercepts:

\

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.

\

Asymptotes:

\

Vertical asymptote:

\

Vertical asymptote exist when denominator is zero.

\

Equate denominator to zero.

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.
