$\"\"$

\

The function is $\"\"$ .

\

Consider the first expression $\"\"$ for $\"\"$ .

\

Construct a table for different values of $\"\"$ , where $\"\"$ .

\

Observe the expression :

\

$\"\"$ for $\"\"$ .

\

Since $\"\"$ is not equal to $\"\"$ , represent the point $\"\"$ with a hallow circle.
