集合是高中数学的基础,函数是高中数学的核心,同学们在学习中应注意理解有关概念的内涵,深入分析集合与函数的基本性质,把握住问题的本质属性,为学好高中数学奠定坚实的基础.本文就集合与函数中易混淆的几个问题逐对解析,希望学生从中受到启发,弄清楚两者的区别.1数集与点集例1 The collection is the basis of high school mathematics, and the function is the core of high school mathematics. Students should pay attention to understanding the connotation of the concept, deeply analyze the basic nature of the collection and function, grasp the nature of the problem, and lay a solid foundation for learning high school mathematics. Basics. This article analyzes several problems that are confusing in the set and function, and hopes that the students will be inspired by it and figure out the difference between the two.1 Number sets and point set examples 1
