Karen Lee Sau Wah and I would like to prepare a flash learning object which explores the relationship between the graphs of y = f(x) and y = f(x + k), where f(x) is in the form of ax^2 + bx + c. As the transformation of the graphs of functions is a new topic in the 1999 Secondary Mathematics which can be found in the coming 334 senior secondary mathematics syllabus, we hope that we can prepare a learning object which can help students to visualize one of the transformation effects (i.e. translation) by changing certain parameter(s), such the values of a, b, c and k.
Difficulties anticipated at this moment:
1. How to make a slider
2. How to draw the gridlines in flash
3. How to draw the quadratic graph

Hi, jaco
I find a webpage about making a slider bar with Flash. See whether it may help.

Hi Jaco,
Thanks for providing the resources about the water cycle to our group. I found a Flash example which may help your group draw the graph desired.

Thanks Martin for your information.
Ryan, thanks for useful link. It definitely can help even though I am a completely novice at flash. The slider can help my group to control the values of different parameters in the final group assignment.
