Homework Help: algebra

Posted by Michelle on Monday, December 6, 2010 at 6:36pm.

I'm doing functions, and I don't know how I'm solving this equation wrong?
the equation is y = (x-2)^2 - 1
when I graph it, the shape is supposed to be a parabola.
I'm using -2,-1,0,1, and 2 as my X values.
But I'm getting 15, 8, 3, 0, and -1 for my Y values, respectively.
