这两种不是函数 函数是一种关系式,一个输入只能对应一个输出,上图中的(c)和(d)一个横坐标对应两个y值的都不是函数。 二. 学会求函数的值域或复合函数(composite function)的值域 对于one to one函数,直接带入定义域的两端点值即可得最大值和最小值 对于many to one函数,需要确定是否有极大值点和极小值...
数学方法参考译文知识点说明:笔者有机会学习了Essential Mathematical Methods3&4(《基本数学方法3和4》,Michael Evans等著,剑桥大学出版社1998年出版),下面是其中第1章“函数和关系”的部分内容的原文及笔者的参考译文,文中的有关复合函数等知识点可供大家在领悟函数教学内容时参考.张东海中学数学教学参考:上半月高中...
