Use the sliders to change A, B, and C 1 - Of A, B, C , which number tells where the curve crosses the Y-axis?
2 - Where does the curve cross the X-axis?
3 - Change C until the curve goes through point F. Show that X and Y for point F work in the formula for the curve.
4 - Keeping A=1, change B and C until the curve passes through all of points D, E, and F (simultaneously).
