$\"\"$

The function is $\"\"$ .

To estimate the value of $\"\"$ , construct a table with nearest values of $\"\"$ .

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

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

Observe the table.

The value of $\"\"$ at $\"\"$ is $\"\"$ and the value of $\"\"$ at $\"\"$ is $\"\"$ .

Therefore the value of $\"\"$ at $\"\"$ is $\"\"$ .

Graph the function.

$\"\"$

Observe the graph.

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