    Sketching graph of polynomial

    How do I sketch the graph of f where f(x)=6+5x-2x^2-x^3

    Can someone give me the steps on how to sketch it?

    1) find the y-intercept
    2) find the zeros of the function (by solving the equation, may require that you depress the equation)
    3) find the number of turns of the function
    4) find end behaviour

    Then you just sketch it- not exactly, but as close as possible.
