^{2}(x+1)", but I can't get this right. The answer shows a cubic graph and it goes from 2,0 to 0,4 then down to -1, 0. now I understand this except the move to 0,4. I know that -2

^{2}is 4, but that is just dealing with first term (x-2)

^{2}. Then we go on with the next term (x+1). I'm really confused with this.
