This is an applet to help you understand more about Quadratic function y=f(x)=A*x²+B*x+C
You can change the value of A,B,C with slider bars and find out how the curve changes.
You can drag the red points when A<>0 (A is not equal to 0.) and find out how it affect those parameters.

If A=0, it become a linear equations. Two intersect points will be shown. You can drag those two points with mouse and find out how B,C change with points.

The slider bar at the right is for changing the scale for the whole system.
