This is a double-sided worksheet over the greatest integer function with notes and examples on one side and practice on the other. The notes begin by defining the greatest integer function and working a few examples using the new notation. Next, a table of values is made and the greatest integer function is graphed. Also, domain and range are determined and can be found before or after the function is graphed (teacher discretion). Finally, 3 examples are graphed using one or two transformations.
