Question 210400
You are OK with your table of values until you got to 4,-1. Since you are dealing with the absolute value of y, it must be positive. When making your table, use the given equation as you did, but take the absolute value of y after you solve for it. So for the case of x=4, y=-1, but abs(y)=1. So when you graph this, you get a "v" shape.
