Step 1:

The expression is $\"\"$ .

Observe the graph.

We can observe that $\"\"$ exists for all values of $\"\"$ except at $\"\"$ .

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

$\"\"$

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

$\"\"$

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

Solution:

$\"\"$ does not exist.
