    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"
  • TracePoly   -- drag point f(x) to state and show new ( x, f(x))
