CRITICAL THINKING
Make a table where the independent variable is the
side length of a square and the dependent variable is the perimeter. Make a
second table where the independent variable is the side length of a square
and the dependent variable is the area. Graph both functions in the same
coordinate plane. Compare the functions and graphs.
