  • 导言:根源和激进功能

    In this chapter, we cover square and cube roots and radical functions. We'll learn how radicals relate to fractional exponents, and see how this knowledge can help us solve radical equations. 
    ::在本章中,我们覆盖平方和立方根和激进函数。我们会了解激进分子与分数指数的关系, 并且看看这些知识如何帮助我们解决激进方程式。

    Like functions studied in previous chapters, these functions have applications in day-to-day life. Whether they are used to measure distances on a baseball diamond or in a video game, to model the speed of the wind or your car as you hydroplane on a road, or even to model the Earth's trip around the sun, radical functions have many practical and important uses. 
    ::与前几章所研究的功能一样,这些功能在日常生活中也有应用。 不管是用来测量棒球钻石或电子游戏的距离,还是用来模拟风速或汽车在路上的水力飞机,或者甚至用来模拟地球绕太阳旅行,激进功能有许多实用和重要的用途。

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