The PolynomialTutor(p) command launches a tutor interface that demonstrates the graphing of the polynomial p.  If the polynomial has any zeroes, they are also displayed.

If p is not specified, PolynomialTutor uses a default function.

If an expression in one variable is specified, the tutor replaces the variable name with x.
