    Help complete a graph?

    Complete the graph of the rational function below based only on the following information and the partial graph with indicated asymptotes:
    f(b+1)<0
    f(a-1)>0

    I have no idea what it wants me to graph. Help?

    How about something like:

    f(x) = \frac{x^2-(a+b)x}{(x+a)(x-b)}-1

    which would have a graph that looked something like the one attached

    (note that when I use a in this post, I'm really using the absolute value of a)
