Help graph

  1. Jul 11, 2005 #1
    help plz...graph

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

    Click here for the question

    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

    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
