Cheung Chun Kay, Jaco 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 ax2 + 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 draw the gridlines in flash
2. How to draw the quadratic graph
3. How to make a slider

I have shared a link about making slider in Flash in Jaco's blog.
Let take a look
