    increasing decreasing function with floor() investigate

    Find where f(x) is increasing and find where it is decreasing
    ** the [] brackets in the power are meant to be the \floor function (i couldn't get it right in latex..)
    Thanks for the help !
    <br />
f(x)=(-1)^{[3x]}X+(-1)^{[2x]}X^2<br /> <br />
