1. The symmetry axis is a straight line X = 1, -b/(2a) = 1, and b =-2a.
a & lt0，b & gt0
y=ax^2+bx+c=y=ax^2-2ax+c
The intersection point (x 1, 0) of the parabola and the x axis satisfies 4 > x 1 > 3.
The other intersection point must be on the negative semi-axis of x, and C >；; 0
abc & lt0，3a+b = 3a-2a = a & lt； 0
4 > x 1 > 3, when x = 4, y must be greater than 0, that is, 8a+c >；; 0
a+b = a-2a =-a & gt； 0
All four conclusions are correct.
