Quadratic function In y = (AX) 2 + BX + C, a determines the opening of parabola b. c.
a. B the symmetry axis of the same sign is on the left side of the Y axis,
a. B is on the right
When B = 0, the axis of symmetry is y-axis
If the vertex is the origin, then B = C = 0
If the parabola passes through the origin, then C = 0
C> The intersection point of 0 parabola and Y axis is on the positive half axis of Y axis
C
