You can put this solution on YOUR website!
I would say the answer is b) $\"y+=+-x%5E2+-+1\"$ . Unless you have a typographical error in your problem, the a) and c) answers both have TWO equal signs. This is not allowed and makes no senses. In the d) answer, there is no y variable. So, I would say the answer is b).\r
