Solution: Let the analytic expression of quadratic function be y = ax2+bx+c∶ and the symmetry axis be x=4∴-b/2a=4? That is, the quadratic function with b=-8a has two intersections with the X axis and one intersection with the Y axis. Let the intersection with the X axis be (x 1, 0, (x2, 0), and the intersection of x2 > x 1 with the Y axis be (0, c). It can be concluded that the base of the triangle formed by x1+x2 =-b/ax1* x2 = c/a is x2-x1x2-x1= √ (x2+x1) 2-4x/kloc.
