The applet allows the user to plot the quadratic function [math]y=ax^2+bx+c[/math] using sliders controlling [math]a[/math], [math]b[/math] and [math]c[/math]. It also displays various information about the function, such as the solutions to [math]y=0[/math] (if real solutions exist), the line of symmetry and the value of the discriminant. An alternative version of the function, in completed square form is also shown.
