Therefore, we can get: 3 = 148 (? 4+2)(? 4a+b)4= 148(4+2)(4a+b)，
Solution: a = 13b =? 20,
So the relationship of quadratic function is: y =148 (x+2) (13x-20).
(2) The functional relationship obtained by (1), the coordinates of point C are (-2,0) and the coordinates of point D are (2013,0).
Points a (-4,3), B (4 4,4),
∴AB=(4+4)2+(4？ 3)2=65，AC=(？ 2+4)2+(0? 3)2= 13，BC=(4+2)2+(4？ 0)2=2 13,
∵ satisfy AB2=AC2+BC2,
△ ACB is a right triangle.
(3) The coordinates of point P exist, and the coordinates of point P are (-5013,3513) or (-12213,28413).
Let p coordinate be (x, 148(x+2)( 13x-20)), then pH =148 (x+2) (13x-20), and HD =-x+200.
① If △DHP∽△BCA, PHAC=DHBC, that is, 148(x+2)( 13x? 20) 13=? x+20 132 13，
Solution: x=-50 13 or x = 2013 (point p is omitted because it is in the second quadrant);
Substitution can get PH=35 13, that is, the coordinate of P 1 is (-5013,3513);
② If △PHD∽△BCA, PHBC=HDAC, that is, 148(x+2)( 13x? 20)52=? X+20 13 has been praised and trampled. What's your comment on this answer?

We know that the image of the quadratic function y=x +bx+c passes through (1, 0) and (2,5), and find the analytic expression of this quadratic function 20 10. Find the analytic expression of quadratic function; 922016-12-01known: quadratic function y=x2+bx+c(b and c are constants). (1) If the image of the quadratic function passes through points A(-2, -3) and B(2, 5), and B(x2, 20 12) is two points on the image of the quadratic function y=ax2+bx+5(a≠0), then when X The analytic formula 720 14-03-27 for finding this quadratic function is known. The image of quadratic function y=x square +bx+c passes through points A (2 2,5) and C (0 0,3) to find the analytic expression of quadratic function 220 13-05-03. The resolution function of the quadratic function in junior high school is Y. Wuhan) The image of the quadratic function y=ax2+bx+c(a≠0) is given, and the following conclusions can be drawn: ① The signs of A and B are the same; ② When x= 1 and x=3, I recommend 2 for you: I especially recommend F.context('cmsRight').
