What is the vertex of the parabola whose equation is y(x 1)2 3?

The equation you provided seems to be missing some elements, but if we assume it is in the form ( y = a(x - h)^2 + k ), where ( (h, k) ) is the vertex, the vertex can be identified directly from the equation. For the equation ( y = (x - 1)^2 + 3 ), the vertex is ( (1, 3) ). If you meant something different, please clarify the equation for a more accurate answer.
