  • 导言:具有多面和函数的操作

    An important class of functions that are used regularly for applications, like modeling your paycheck, or the path of a home run, or the growth or decline of a population, are polynomial functions. They are so important we have already discussed some examples of polynomials extensively—horizontal lines (degree 0 polynomials) and lines with positive or negative slope (degree 1 polynomials).
    ::通常用于应用的重要功能类别,如模拟你的薪酬,或本垒打路径,或人口的增长或下降,是多式功能。 这些功能非常重要,我们已经广泛讨论了多式横向线(度0多式线)和正或负斜度线(度1多式线)的一些例子。

    In this chapter, we will cover operations with polynomials—addition, subtraction, multiplication, and division. We will also generalize these operations to other functions and explore an operation for functions called composition.
    ::在本章中,我们将涵盖多门类行动——附加、减法、乘法和划分;我们还将把这些行动推广到其他职能,并探讨所谓组成职能的行动。

    By the end of this chapter, you should be able to:
