Homework Help: Alg. 2

Posted by Miley on Wednesday, February 13, 2008 at 4:50pm.

I know how to graph polynomial functions, but i'm having a hard time getting the second point on this one.

f(x)=x(x-1)(x+2)(x+2).
I graphed my zeros and made the right arrow go up and the left arrow go down. I plotted my first point by pluggin in -1. My first point is (-1,2). On my answer sheet there is a point at (1,-1.5). How do i know that i need to solve for another point? And how to i get the point (1, -1.5)?
