Use the sliders for a, b, and c to discover the number of x-intercepts for the quadratic function.
Move the sliders until you get a curve that cuts the x-axis at 2 points.[br]Find other curves with different values of a, b and c that cuts the x-axis at 2 points.[br][br]What do you observe about their discriminant?
Move the sliders until you get a curve that touches the x-axis at 1 point.[br]Find other curves with different values of a, b and c that cuts the x-axis at 1 point.[br][br]What do you observe about their discriminant?
Move the sliders until you get a curve that does not touch the x-axis at all.[br]Find other curves with different values of a, b and c that does not touch the x-axis at all.[br][br]What do you observe about their discriminant?
