函数图象(曲线)交点问题是高中数学的一个重要课题,它涉及到数学中的数形结合、函数方程等思想方法,是学习的重点,也是考查的热点.下面研究一下函数与其反函数的交点性质及应用.
The intersection of function images (curves) is an important topic in high school mathematics. It involves mathematical methods such as combination of number and shape, function equations, etc. It is the focus of study and is also a hot spot for examination. The following is a study of functions and their inverse functions. Intersection nature and application.
