The limit of the function is $\"\"$ .

The function is $\"\"$ .

Construct the table for different values of $\"\"$ , to estimate the value of $\"\"$ :

\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \

$\"\"$	\ $\"\"$ \	\ $\"\"$ \	\ $\"\"$ \	\ $\"\"$ \	\ $\"\"$ \	\ $\"\"$ \
$\"\"$	$\"\"$	$\"\"$	$\"\"$	$\"\"$	$\"\"$	$\"\"$

\ \

Observe the table.

\ \

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

$\"\"$ .

As $\"\"$ tends $\"\"$ from right side, the value of $\"\"$ approaches to $\"\"$ .

$\"\"$ .

Left side limit and right side limit are equal, $\"\"$ is exist.
