Math calculation for senior high school entrance examination 100
Solution: (1)∵ The vertex of the parabola is C(4, -2),

The symmetry axis of parabola is x=4.

Let the analytical formula of parabola be y=a(x-4)2-2, then a(0-4)2-2= 1, then a=3/ 16,

The parabola is y= 16/3(x-4)2-2.

(2) How did the condition move without writing all Q points?
