1、2019-2020 年高一数学上 3.4 函数的单调性学案沪教版【教学目的】1 使学生理解增函数、减函数的概念，掌握判断某些函数增减性的方法；2 培养学生利用数学概念进行判断推理的能力和数形结合，辩证思维的能力；【基本知识】1、定义：对于给定区间上的函数f(x)及属于这个区间上的任意 两个自变量x1、x2，当x1x2时，如果有f(x1)f(x2)，则称 f(x)在这个区间上是函数，这个区间就叫做函数f(x)的区间；如果有 f(x1)f(x2)，则称 f(x)在这个区间上是函数，这个区间就叫做函数f(x)的区间；说明1。单调区间是定义域的子集；2。若函数 f(x)在区间 D上是增函数，则图象在D
2、上的部分从左到右呈趋势若函数 f(x)在区间 D上是减函数，则图象在D上的部分从左到右呈趋势3。单调区间一般不能并2、判断单调性的方法：定义；导数；复合函数单调性：同增则增，异增则减；图象3、常用结论：两个增（减）函数的和为_；一个增（减）函数与一个减（增）函数的差是_；奇函数在对称的两个区间上有_的单调性；偶函数在对称的两个区间上有_的单调性；互为反函数的两个函数在各自定义域上有_的单调性；【课前预习】1 下列函数中，在区间(，0)上是增函数的是 ()A、B、g(x)=ax+3(a0)C、D、2 函数的单调递增区间是3 函数 f(x)logax（0a1）的单调增区间是4 函数)23(log)
