Basic concepts of quadratic function What a stands for, B stands for, C stands for! There are also related formulas!

A is the quadratic coefficient, which is responsible for the opening direction of the parabola
B is the coefficient of the first term, which is mainly responsible for the axis of symmetry
C is a constant term, and the intersection point with y axis is (0. C)
Formula: vertex coordinates (- B / 2a, 4ac-b ^ 2 / 4A)
The axis of symmetry is a straight line x = - B / 2A
