Investigating the general parabola

Alter the parameters to see the effect on the parabola. Also shows the discriminant, y-intercept, coordinates of roots, axes of symmetry and the coordinate of the vertex. With some questions to promote investigation and discussion amongst mixed-ability groups. I use this to introduce quadratics and every student is able to offer something to the discussion from if the a parameter is negative it's a sad face, right up to the locus of vertex forming a parabola as the b parameter is altered.
