The limit expression is $\"\"$ .

Let $\"\"$ .

Graph :

Graph the function $\"\"$ :

$\"\"$

Observe the graph :

As $\"\"$ tends to $\"\"$ from both sides, the function $\"\"$ approaches to $\"\"$ .

$\"\"$

Draw the table for several values of $\"\"$ near to $\"\"$ .

Observe the table :

As $\"\"$ tends to $\"\"$ from both sides, the function $\"\"$ approaches to $\"\"$ .

Hence $\"\"$ .
