分段函数是函数大家族中的一个重要成员,由于它具有特殊的表达形式以及特殊的考查功能:函数分段给出,可以为多种函数的综合提供一个平台;可以与函数的奇偶性、单调性、周期性、对称性、图像、最值、不等式以及绝对值函数等问题相结合来考察学生的综合能力。解题时还可以重点考查分类讨论、数形结合等数学思想,因此值得我们去研究分段函数考查的题型及方向。本文就分段函数的
Piecewise function is an important member of the large family of functions. Because of its special form of expression and special examining function, the function of subsection is given in a piecewise manner, which can provide a platform for the synthesis of many kinds of functions. It can be combined with the function’s parity, Monotonicity, Periodicity, Symmetry, Image, Most Significant, Inequality, and Absolute Value Functions to examine students’ comprehensive abilities. Problem-solving can also focus on examining the category discussion, mathematical combination of mathematical ideology, it is worth us to study the test type and direction of the piecewise function test. This article on the piecewise function
