    Do you know how to graph x³ - 4x² - 3x + 18?

    Just graph all positive part. for negative, flip it over x-axis. For example: |dw:1358726318953:dw| See what I mean?

    Sort of, but if I were to flip the negitive part over the x-axis, wouldn't it look like|dw:1358726494656:dw|

    NO, just left positive value of y alone,|dw:1358726518903:dw|

    So to graph this, is there anything I have to show, so as to prove that it is an absolute function?

    Yes, just have all negative values flip over x-axis. Not sure exactly what you mean, there is nothing to prove.
