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.
