- Let's say we have two equations for and for . Combine these two equations and we get one piecewise equation as below.
Now, try to drag point A across y-axis. You'll find that point A will 'jump' from the left line to the right when x = 0. Now, click on 'View Domain' and you'll find that a pink point appears on the x-axis. If you drag point A away from the previous position, the pink points showing the domain on the x-axis. If you want to view the range on the y-axis, simply click on 'View Range'.
- For the second piecewise equation
- For the third piecewise equation
