Transforming functions (sliders for stretches/shifts)
- Author:

The applet allows you to use sliders to change the variables a, h, and k. The changes equate to shifts in the various graphs (quadratic, absolute value, square root, and rational functions).
Students should explore the various sliders and functions and ask themselves:
1) What effect does a negative/positive change of a have?
2) What effect does a negative/positive change of h have?
3) What effect does a negative/positive change of k have?
If you understand these shifts you can use the properties on many, many, graphs.
