y = x^2, vertex lies at (2,-3) open negative direction
Beginning with the function y =x^2, which of the following shows the changes you would make so that the vertex lies at (2,− 3) and the parabola opens in a negative direction?

my answer is y=-(x-2)^2 +3 am i correct?
No.
For any quadratic of the form , it's vertex lies at . In other words, the x co-ordinate changes sign, but the y co-ordinate does not.
