There are some numbers, the perfect squares, that we would ideally be using for a table of values: the square root of zero = 0, sqrt of 1 = 1, sqrt of 4 = 2, and sqrt of 9 = 3. With those values in mind, our goal in creating a table of values can be to make our radicands, or values under the square root sign, equal to 0, 1, 4, and 9. Here we use "clever" xinputs to generate a table of values in order to graph square root functions.
