The function is $\"\"$ .

Graph of the function $\"\"$ :

$\"\"$

Observe the graph.

End behavior of the graph:

$\"\"$ and $\"\"$ .

Support numerically :

Construct a table that shows the values to investigate the function values as of $\"\"$ increases.

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

Observe the table:

As $\"\"$ tends to $\"\"$ , $\"\"$ approaches $\"\"$ and as $\"\"$ tends to $\"\"$ , $\"\"$ approaches to $\"\"$ .

End behavior : $\"\"$ and $\"\"$ .
