The image of quadratic function y=(x- 1) 2 +2 rotates 180 degrees around the origin, and the analytical formula of the image is _ _ _ _ _ _.
Quadratic function y=(x- 1) 2 +2 vertex coordinate is (1, 2),
The vertex coordinates of the quadratic function image obtained by rotating 180 around the origin are (-1, -2).
Therefore, the analytical expression of the rotated new function image is y =-(x+ 1) 2-2.
