Make a quadratic graph
This can be used as a template for making different examples of quadratic graphs (by dragging the free points A,B,C).
It can also be turned into an open activity in the GeoGebra Classroom. A simple question can be:
Show me a quadratic graph/function that:
- touches the x-axis and has a positive y-intercept;
- has a maximum point and cut the x-axis on different sides of the y-axis;
- has a positive discriminant and a negative sum of roots;
- ......
