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

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.
