Take 92? 3b+c=6 12？ b+c=0。 ,
Solve b =? 1c=？ 32.,
∴ The analytic formula of quadratic function is y = 12x2? x？ 32.
(2) Let y=0 and get 12x2? x？ 32 = 0, what's the solution? x 1=- 1，x2=3，
The coordinate of point c is (3,0),
∫y = 12 x2？ x？ 32= 12(x？ 1)2? 2,
The coordinate of vertex p is (1, -2).
The intersection point A is AE⊥x axis, the intersection point P is PF⊥x axis, and the vertical feet are E and F respectively.
Easy to get ∠ ACB = ∠ PCD = 45.
AC = AE2+CE2 = 6 I praised it and stepped on it. What's your comment on this answer?
