The function is $\"\"$ .

Find $\"\"$ .

Graph the function:

$\"\"$

Observe the graph:

As $\"\"$ tends to $\"\"$ from left hand side, $\"\"$ approaches to $\"\"$ .

As $\"\"$ tends to $\"\"$ from right hand side, $\"\"$ approaches to $\"\"$ .

Since the right hand limit and left hand limit are not equal, limit does not exist.

$\"\"$ does not exist at $\"\"$ .
