    1. Use Descartes` Rule of Signs to determine the possible number of positive real zeros of the function.
    F(x)=3x cube-4x squared-2x-4

    ***************x squared +11x+28
    2. Graph: f (x)= ------------------------
    ***************x squared +8x+16

    ****************3x squared -3x-1
    3. Graph: f (x)= ------------------------
    ***************x squared -x-2
