函数是高中数学的一个重要基本概念，一直是高考的考察重点。而最近几年高考不是直接对函数进行考察，而是倾向于通过其它知识要点，通过转换思想，利用函数的性质和图像来解答，这样不仅考查了考生对函数知识的掌握，也考查了学生的数学思维能力.函数思想是函数理论的升华。在历年高考题中，函数思想在一些题目的作答过程中得到了很好的体现,例如在解不等式、数列、方程、解析几何等相关问题的时候都有可能会用到函数，通过利用函数的最值、单调性等性质及函数图像针对性的对相应问题进行解答，而用函数思想解题充分的体现了数学转化思想.
Function is an important basic concept of the high school mathematics, has been
the focus of the college entrance examination investigation. And in recent years
the university entrance exam is not directly on the function, but tend to by
other knowledge points, through the transformation idea, the nature of the use
function and image to answer, such not only examines the examinee the function
of the master of knowledge, also examines the mathematics thinking ability of
students. The function thought is the sublimation of function theory. Function
in the calendar year the university entrance exam questions, thinking in the
process of answer some questions are well reflected, for example in solving
inequality, sequence, and resolution of equation, how a few related issues are
likely to use function, through the use of function of the value, monotonicity
properties and functions such as image corresponding to the appropriate question
answer, thought and function fully embodies the transformation of mathematics
thought to solve problems.追é®
