    Start at X = 0. Y = 2 - 0 - 0^3 -> Y = 2. So you put a point at (0, 2).

    Then go to X = 1. Y = 2 - 1 - 1^3. -> Y = 0. So you put a point at (1, 0).

    So on, so forth. Just calculate each X point separately and draw a point wherever you have an X = Y situation. Then link all the points with a line.

    Perhaps make up a table :-

    x___- 3____-2____-1____0___ 1____2____3

    y___32____12____4____2____0___-8____-28

    Plot these points
