Parabols, Quadratic Functions
parabola -- Multi page: 2 parabolas: 1 in general form, 1 in standard forms,
* both generated by equations defined by parameters.
* WITH SHOW/HIDE ACTION BUTTON
* graphs of 2 parabolas: 1 in general form, 1 in standard forms,
* 1 parabola, set a, then generat parabola w/2 points.
* 1 parabola controlled by 3 points, used for determinant analysis
* 1 vertical axis of symmetry, 1 horizontal "axis of symmetry"

Spread Sheets -- Dynamic Computation
polynomial spreadsheet -- * graph polynomial function written in factored form * complete synthetic division computation
quadratic -- * enter a, b, c, get x1, x2, h, k * enter a, h, k, get x1, x2, a, b, c, and the discriminant
