(1) According to the meaning of the title, there are: C = - 64 − 2B + C = 0, the solution is b = - 1C = - 6; ∪ y = x2-x-6 = x2-x + 14-254 = (X-12) 2-254; ∪ the vertex coordinates of the parabola are (12, - 254); (2) from (1), we know that the analytical formula of the parabola is y = (X-12) 2-254; translate it to the left along the X axis by 52 single bits
