Help graph

help plz...graph

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.

Yu Just Gave All The Conditions For The Graph. Take A Min Athink About It. First Draw Your Assmytopes, Then Insert Your Critical Points And So On
 
here is what i get for the graph. can someone please verify it.

that looks about right, i matched up the data given and ur graph...and seems kinda accurate....one thing is that....ur f(-2) doesnt seem to be a point of inflection in ur graph its just going up... without changing direction or anything...so i think u might want to fix that
