\

The limit expression is $\"\"$ .

\

Consider the function as $\"\"$ .

\

Graph the function $\"\"$ .

\

$\"\"$

\

Observe the graph:

\

As $\"\"$ approaches to $\"\"$ , the function approaches to $\"\"$ .

\

$\"\"$

(b)

\

Consider $\"\"$ .

\

$\"\"$

\

Apply L $\"\"$ Hospital $\"\"$ s Rule.

\

L $\"\"$ Hospital $\"\"$ s Rule: If $\"\"$ or $\"\"$ then $\"\"$ .

\

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

\

Apply L $\"\"$ Hospital $\"\"$ s Rule again.

\

$\"\"$

\

Apply L $\"\"$ Hospital $\"\"$ s Rule again.

\

$\"\"$

\

Therefore, $\"\"$ .
