    More fun with functions

    If you would like to still help I have some more that I am working on. Here are the stipulations.
    the limit as x appraches negative infinity=-1
    the limit as x approaches -2 from the negative= infinity
    the limit as x approaches -2 from the positive= negative infinity
    the limit as x approaches 2= infinity
    the limit as x approaches infinity=-1
    x intercepts only at x=4,0,-3
    verticle asymptotes at x=-2,2

    Construct this as a rational function. I would suggest:

    <br />
f(x)=-\ \frac{(x+3)x(x-4)}{(x-2)^2(x+2)}<br />
