is the standard form of a quadratic equation. Move quadratic b. Quadratic b has a maximum point since its term in negative. Move quadratic c. Quadratic c has a minimum point since its term in positive. The dashed line going through the maximum or minimum point is the quadratic's axis of symmetry. The axis of symmetry divided the quadratic into equal halves.
