Analytic expression of quadratic function determined by vertex coordinates I have learned the analytic formula of quadratic function to determine the vertex coordinates, for example, y = 2 (x-1) + 2, and the vertex coordinates are (1,2). Can we find the vertex coordinates of the analytic formula of quadratic function y = AX2 + BX + C (1.2) on the other hand It's too much trouble for the second floor on the premise that a is the fixed value

It can all be the same parabola
