The function is $\"\"$ , at $\"\"$ .

Continuity Test condition 1:

Find if $\"\"$ exists.

Substitute $\"\"$ in $\"\"$ .

$\"\"$

The function is defined at $\"\"$ .

Continuity Test condition 2:

Find if $\"\"$ exists.

Construct a table that shows the values of $\"\"$ for $\"\"$ -values approaching $\"\"$ from the left and from the right.

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

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

Observe the table values, as $\"\"$ tends to $\"\"$ from the left and from the right , $\"\"$ approaches to $\"\"$ .

$\"\"$ .

Continuity Test condition 3: Check $\"\"$ .

Observe above two conditions,

Since $\"\"$ , $\"\"$ is continuous at $\"\"$ .

$\"\"$ is continuous at $\"\"$ ; $\"\"$ , $\"\"$ and $\"\"$ .
