Step 1:

The expression is $\"\"$ .

Graph the function $\"\"$ .

Observe the graph.

$\"\"$ exists for all values of $\"image\"$ except at $\"\"$ .

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

$\"\"$

As $\"image\"$ 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.
