Quadratic polynomials ax^2 + bx + c

Functions
Move the sliders "a", "b", and "c" to change the values of p(x) coefficientes. What's the effect on the graph when you move slider "a"? What kind of polynomial is when a = 0? What's the effect on the graph when you move slider "b"? What's the effect on the graph when you move slider "c"? I created it to help my students to visualize the effect on thegraph of a quadratic polynomial wen they change its coefficients. Hope you find it useful to. There are a lot of questions you may ask them, for instance, what happens with the graphic if the leader coefficient is zero?
