Domain and Range of Functions

Press the Play button in the bottom left corner to activate point A. Point A will then oscillate along the x-axis. Point B will follow the elements in the domain. The restricted domain will be highlighted in red. Point C will follow the elements in the range. The range will be highlighted in blue. You can change the functions by typing it into the input box.
Did you zoom out and find the same domain? When you zoomed out did you find the same range? What happened when you changed the function?
