Students often view questions about polynomials—finding the zeros of a polynomial function, solving a polynomial equation, factoring a polynomial, or writing a polynomial function given certain properties—as discrete, unconnected processes. To address students' confusion about the many directions given for working with polynomial functions and to enable them to gain a true, conceptual understanding of polynomial functions, I created a graphic organizer (see **fig. 1**).
