\

The function is \"\".

\

Graph the function:

\"\"

\

Observe the graph:

\

As \"\" tends to \"\" from the right hand side, the function approaches to \"\".

The function is \"\".

\

Factorize the denominator.

\"\"

\

Cancel the common terms.

\

\"\"

\

When we approaches \"\" from the right , \"\" is a small positive number .

\

Thus , the quotient \"\" is a large positive number and \"\" approaches infinity from the right \"\".

\

\"\".

\

\"\" increases without bound as \"\" approaches \"\" from the right.

\

We can verify the limit by the below table .

\

A limit in which \"\" increases or decreases without bound as \"\" approaches \"\" is called an infinite limit.

\

As \"\" tends to \"\" from the right hand side, then the limit approaches to \"\".
