For example, if the graph is a graph of quadratic function, the equation AX2 + BX + C = 3 of X follows? The graph is the axis of symmetry, and the ordinates are 3, A0, C > 0

But in fact, the relationship with a, B, C is not very big, but the relationship between function and equation can be seen as follows: if there are two functions f (x) and G (x), they form the equation f (x) = g (x), then the root of the equation is the X coordinate of the intersection of two function images. For example, in this problem, f (x) = AX2 + BX + C, the equation is AX2
