Step 1:

Condition (2): $\"\"$ exists.

Observe the graph.

Left hand limit :

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

$\"\"$ .

Right hand limit :

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

$\"\"$ .

Left hand limit and right hand limit are equal, limit exist.

$\"\"$ .

$\"\"$ exist.

Step 1:

The limit expression is $\"\"$ .

$\"\"$

Solution:

$\"\"$
