Quadratic Functions
- Scaling a Quadratic Function
* Scaling a quadratic function f(x) = ax2 where a is positive number.
Use this interactive file to learn how to scale a quadratic function. Investigate the effect of changing the coefficient of the x2 term has on the graph of the function.
Instructions:
- Use in conjunction with the corresponding student activity.
- Drag the slider to change the coefficient of the x2 term.
- Use the check boxes to show the roots, the turning point and the intersection between the function and a line.
