Step1:

The expression is $\"\"$ .

Graph the function $\"\"$ .

Observe the graph.

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

$\"\"$

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

$\"\"$

Since the left hand limit and the right hand limit are equal, limit exist.

Solution:

$\"\"$ .
