$\"\"$

The function is $\"\"$ .

Observe the given graph.

There are vertical asymptotes at multiples of $\"\"$ .

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 undefined.

Therefore limit does not exist.

$\"\"$

Limit does not exist.
