Previously you have learned……. Definition of a Quadratic Function:A quadratic function is a second‐degree polynomial function. The graph of the quadratic function is called a “parabola.” The standard form of an equation of a parabola is
.
All parabolas are symmetric with respect to a line called the axis of symmetry. To find the axis of symmetry for a parabola written in standard form, use part of the quadratic formula
.
