Equations of Parabola Function
- GeoGebra Materials Team
Drag the Form slider to see three different forms. Drag the lower parameter sliders to change the parabola. See the accompanying Word document for more information.
In the factored form, with slider a being positive, it's impossible to make the vertex rise above the x-axis by dragging the sliders. And when slider a is negative, it's impossible to make the vertex drop below the x-axis. Why?
