# Thread: Help complete a graph?

1. ## 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?

2. Help anyone?

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)
