Build & Fit - absolute value f'n I
- Judah L Schwartz
You can make an absolute value function by dragging the RED points almost anywhere on the screen (why almost?). The function will have the form Now try to build the same absolute value function by using the BLUE sliders. Try to do this without displaying the functional form of the RED absolute value function you have made. You can check your work by showing the expressions for the functions on the screen. [ compare & contrast with the applet "Build & Fit - absolute value f'n II"] What questions could/would you pose to your students based on this applet ?
