Answer:
The minimum value of y=-6 ----> is not ok. The axis of symmetry is x=3 ----> is ok. case 4) we have. This a vertical parabola open upward (the leading coefficient is positive)---> is ok. The vertex represent a minimum ---> is ok. The vertex is the point (3,3) The minimum value of y=3 ----> is ok. The axis of symmetry is x=3 ----> is ok
