Quadratic Inequalities
 
The applet demonstrates how the quadratic inequalities in the form


ax 2 + bx + c > 0 or ax 2 + bx + c < 0
are solved graphically.

Enter the values for a, h, and k and choose whether y > 0 and y < 0. Press "Draw" button. The applet will display the graph of
y = ax 2 + bx + c
, and the solution to the inequality will appear in red on the x-axis.
