(a)

The function is $\"\"$ .

Graph :

Graph the function $\"\"$ :

$\"\"$

Observe the graph.

As $\"\"$ tends to large positive number, then $\"\"$ approaches to $\"\"$ .

Hence $\"\"$ .

$\"\"$

(b)

The function is $\"\"$ .

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

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

Observe the table.

As $\"\"$ tends to large positive number, then $\"\"$ approaches to $\"\"$ .

Hence $\"\"$ .

$\"\"$

(a) Using the graph the value of the limit is $\"\"$ .

(b) Using the table of values then the limit is $\"\"$ .
