X 1=3，x2 =- 1。
∫m < n，
∴m=- 1，n = 3...( 1)
∴A(- 1,- 1),B(3,-3).
Let the analytical formula of straight line AB be y = KX+B.
∴? k+b=？ 13k+b=？ 3,
Solution: k =? 12b=？ 32,
Therefore, the analytical formula of straight line AB is y =-12x-32;
Let the analytical formula of straight line OB be y=kx,
∴3k=-3，
Solution: k=- 1,
∴ The analytical formula of straight line OB is y =-x;
(2)∵ The parabola passes through the origin, and the analytical formula of the parabola is y = AX2+BX (a ≠ 0).
∴a？ b=？ 19a+3b=？ 3,
