高中数学回归教材系列2函数与基本初等函数
点蓝色字关注“相形见数”
函数是高中数学的主干内容，高考对本章考查的内容主要有：
①结合函数的定义综合考查函数的基本性质；
②结合一元一次不等式、一元二次不等式、指数与对数不等式考查函数的定义域；
③考查用待定系数法、换元法等求解函数的解析式；
④考查指数函数、对数函数、二次函数、幂函数的图像和性质；
⑤结合函数的图像考查函数的性质、函数的零点与方程的根；
⑥结合实际问题考查函数的应用.
函数的基本性质与应用是高考的高频考点，以选择题或填空题为主，分值大约 10 分.
本章内容一般不会出现单一知识点的考题，常结合函数的单调性、奇偶性、周期性命题，或将函数的性质融入函数的图像进行考查，本章内容也可能与导数、不等式等结合命题.
