The polynomial function is
.
Rewrite the function as
.
Find the intercepts :
\Find
- intercepts by equating
to zero.

and 
and 
Imaginary values are not consider, so the
- intercep is
.
Find the
- intercept by substituting
in
.

The
- intercept is
.
Make a table to find the ordered pairs.
\Choose different values of
and find corresponding
values.
