Here is a question i am havin a bit of trouble with.

http://img125.imageshack.us/img125/8824/cs2rr.jpg [Broken]

This is what i figured out:

f'(1) must be a local max or min since hte derivativee is 0

the second line are the vertical and horz assympotes.

there is a vertical assymptote at x=0

there is a horizontal assymptote at y=-4 and y=-1

f(-2) is the point where changes concavity

concave down -2<x<0

Concave up x<-2 or x>0

I am unsure of how to draw this graph. thanks for your help in advance.
