This applet shows a few piecewise defined functions. Clicking next will advance through these options.

is the sign of ,
A left function and a right function where you can define both functions and move the split point
is which rounds down to the next integer
is which rounds up to the next integer
A function with 3 piecewise components

Clicking the next button will advance to the next function.

For each function move the

value and notice what happens with the

value. What happens when

is located at a hollow circle? For the

and

split function what happens at

? What is the significance of filled and closed circles?
