#### Solution Preview

The domain is just the all the x-values and the range is just the y- values

For example in the problem above:

Graph the function =

f(x) = x-2/x^2 - 3x + 2

Domain Range

-10 -0.27

-4 -.2

-2 -.25

-1 -.33

-1/2 -.5

0 -.66

1/2 2

1 undefined

2 0

3 1/2

4 1/3

10 1/9

Set the denominator equal to zero, and solve for X ...

#### Solution Summary

The domain and range are values for the polynomial equation. The domains is really all the X values. The range is all the Y values.
