Different Forms of the Quadratic Function

GeoGebra File 1 - Quadratic Function in Standard Form

Use this interactive file to understand how changes to a quadratic function affects its graph.

Instructions:

Use in conjunction with corresponding student activity.
Drag the sliders to change the quadratic function.
Use the check boxes to show the graph of the parent function g(x) = x2 and the tangent to the graph at its turning point.

GeoGebra File 2 - Quadratic Function in Factor Form

Use this interactive file to learn how the roots of a quadratic function relate to the function.

Instructions:

Use in conjunction with the corresponding student activity.
Drag the sliders to change the roots of the quadratic function.
Click on the check box to show the graph of the parent function g(x) = x2

GeoGebra File 3 - Quadratic Function in Vertex Form

Use this interactive file to learn how changes to the function affect its graph.

Instructions:

Use in conjunction with the corresponding student activity.
Drag the sliders to change the quadratic function.
Click on the check box to show the graph of the parent function f(x) = x2
