Four identical squares are cut from the corners of a piece of blue paper measuring 8 cm by 8 cm.

What are the valid values of p?
Create a function A(p) that maps the value of p shown on the slider to the Area Remaining, remember to state the domain with the function.
Graph the function for values of p in the domain.
State the range of the function.
