[math]y=ax^2+bx+c[/math] is the standard form of a quadratic equation. Move quadratic b. Quadratic b has a maximum point since its [math]ax^2[/math] term in negative. [br][br]Move quadratic c. Quadratic c has a minimum point since its [math]ax^2[/math] term in positive. [br][br]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.
