Domain and Range of a Function

This applet can be used to demonstrate the concept of Domain and Range of a function.
  • Click on a button to select one of the three functions.
  • Drag the "domain" slider. A vertical ray will scan the viewing window and will project the intersection point of the ray and  the function to the x-axis. The domain appears as red interval(s) on the x-axis.
  • Drag the "range" slider. A horizontal ray will scan the viewing window and will project its intersection  points with the function to the y-Axis. The range appears as green interval(s) on the y-axis.
