高中数学中,各分支学科的研究对象及研究问题的方法不同,且多种多样,但它们之间又相互渗透,彼此有一定联系却又不容易被发掘.函数概念使现实世界中量与量之间相互联系、相互制约的关系在数学中得到反映.它反映了一个事物随着另一个事物变化而变化的关系和规律,是培养学生辩证唯物主义观点、解决实际问题能力的有力工具.函数是近代数学的主要基础,也是高中数学的一根主线,是高中数学问题的主要载体之一,它与方程、不等式、
In high school mathematics, the research objects of different branches and the methods for researching problems are different and varied, but they infiltrate each other and have certain connections with each other, but they are not easy to be discovered. The concept of functions makes quantity and quantity in the real world. The relationship between mutual connection and mutual restraint is reflected in mathematics. It reflects the relationship and laws of a thing that changes with the change of another thing. It is a powerful tool to cultivate students’ dialectical materialism and solve practical problems. It is the main foundation of modern mathematics, and it is also a main line of high school mathematics. It is one of the main carriers of high school mathematics problems, and it is related to equations, inequalities,
