Image error

"This graph is symmetric respect with the origin because if flipped upside down, the graph looks the same as it does right-side up"

I flipped it upside down, it did not look the same. What's wrong? If I rotate it 180 degrees around the origin, it does look the same. If I reflect it through the X axis, aka turning it upside down, the curves have moved to different quadrants. —Preceding unsigned comment added by 121.222.246.148 (talk) 03:53, 1 July 2008 (UTC)

Thanks for catching that error. I have fixed the image. -- penubag  (talk) 07:36, 1 July 2008 (UTC)

You had it right the first time. In the picture you have now the shapes are symmetric with respect to the X axis. NOT with respect to the origin.EliBerger (talk) 13:18, 2 July 2008 (UTC)
