Change the value of the sliders and explore the connection between the value of the discriminant and the roots of a quadratic function.
What is the value of the discriminant when the graph crosses the x-axis twice?
What is the value of the discriminant when the graph crosses the x-axis once?
What is the value of the discriminant when the graph crosses the x-axis zero times?
