    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.
