(a)

The limit is $\"\"$ .

The function is $\"\"$ .

Graph :

Graph the function $\"\"$ :

$\"\"$

Observe the graph.

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

$\"\"$ .

(b)

The function is $\"\"$ .

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

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

Observe the table.

As $\"\"$ closes to negative large number then $\"\"$ approaches to $\"\"$ .

$\"\"$

(c)

The limit is $\"\"$ .

Rationalize the function.

$\"\"$

Since $\"\"$ then $\"\"$ becomes $\"\"$ .

$\"\"$

Quotient law of limit : $\"\"$ , if $\"\"$ .

$\"\"$

Sum law of limit : $\"\"$ .

$\"\"$

Root law of limit : $\"\"$ .

$\"\"$

Theorem : If $\"\"$ is a rational number then $\"\"$ .

$\"\"$
