Exploring Properties of Quadratic Equations

Use the dynamic image to explore properties of a quadratic function. Use sliders a, b, and c to adjust the values of the coefficients. You can also use the check boxes to Show/Hide different elements of the image. Questions to Answer: 1) When does the parabola open up? When does it open down? 2) What happens when a = 0? 3) Where are "zeros" found? How many does your parabola have? Does it always have that many?
