Question In this exercise you will be adopting the concept of composition to model polynomials. A polynomial is a mathematical function composed of unit expressions called terms. The following is an example of a single-variable polynomial. 5x - 2x + 7 Notes: a polynomial may have one, two or more variables. However, in this exercise, the scope is limited only to single-variable polynomials. Each term of a polynomial contains a coefficient and an exponent. The polynomial from the above example has three terms and their coefficient and exponent are shown in Table 1. Table 1 Term Coefficient Exponent 5r 5 -2 7 7 2 - 2x 1 0 Then, a single-variable polynomial can be modeled with two classes as shown in Figure 1 and their descriptions are given in Table 2.
