1、函数一、函数()yf x及有关性质。1.函数定义：()yf x中，自变量x的取值范围为函数的定义域。当xa时，()yf a叫函数值。所有函数值的集合叫做函数的值域。2.映射的定义：:fAB两个允许：两个不允许：3.同一函数：_相同。_相同。值域相同。（可由得）4.函数定义域求法：使函数有意义的条件。整式函数（一次函数、二次函数）定义域为R。分式函数的分母不为0。偶次根式函数，被开放数大于或等于0。（()f x的()0f x）对数函数的底数大于0 且不等于1，真数大于0。有多个限制条件的转化为不等式组求定义域。5.函数的单调性：定义：逆运用：当()yf x在区间 m，n上为增函数时，若()()f

2、xf g x则有：()()()()xg xxng xm当()yf x在区间 m，n上为减函数时，若()()fxf g x则有：()()()()xg xxmg xn常用函数的单调性：.一次函数ykxb，当0k时为增函数；当0k时为减函数。.二次函数2yaxbxc，当0a时在(,2ba为减函数；在,)2ba为增函数。当0a时在(,2ba为增函数；在,)2ba为减函数。与开口方向和对称轴有关。.反比例函数1yx在,00与，上均为减函数；1yx在,00与，上均为增函数。.xya01aa且，当01a时为减函数；当1a时为增函数。.logayx01aa且，01a时，在0,上为减函数；当1a时，在0,上为增

3、函数。6.反函数：求函数()yf x的反函数的方法：|精.|品.|可.|编.|辑.|学.|习.|资.|料.*|*|*|*|欢.|迎.|下.|载.第 1 页，共 9 页（1）先根据原函数的定义域求出其值域（2）由()yfx解出()xy（3）将()xy中的,x y互换，即得反函数1()yfx标明定义域有关性质：（1）原函数()yf x与反函数1()yfx的定义域和值域正好互换，原函数过点,a b，则反函数过点,b a。（2）互为反函数的图象关于yx成轴对称图形。（3）原函数与反函数的单调性相同。7.函数得奇偶性：存在奇偶性得条件时定义域必须关于原点对称，在定义域内，将xx换成后（1）若()()fx

4、fx，则()yf x为偶函数。（2）若()()fxf x，则()yf x为奇函数。有关性质：（1）偶函数得图象关于y轴对称，在对称区间上的单调性相反。（2）奇函数得图象关于原点对称，在对称区间上的单调性相同。8.求函数值域的基本方法（1）利用函数的单调性求值域：若()yf x在,m n上为增函数则其值域为(),()f mf n若()yf x在,m n上为减函数则其值域为(),()f nf m。（2）配方法：二次函数2224()24bacbyaxbxca xaaxR当0a时，有最小值244acba，值域为244acba，；当0a时，有最大值244acba，24,4acba。（3）反表示法：即利用

5、反函数的定义域既为原函数的值域。例如：求2121xxy的值域。（4）换原法：还原注意新元素的范围。例如：求1yxx的值域。（5）判别式法：形如：21112a xb xcyaxbxc类型，可转化为关于x的一元二次方程有解，0求值域。（6）图象法。9.周期性：若函数()yf x对于最小正周期T，使()()f xTf x，则称T为函数()yf x的最小正周期。|精.|品.|可.|编.|辑.|学.|习.|资.|料.*|*|*|*|欢.|迎.|下.|载.第 2 页，共 9 页文档编码:CG8L2U6L7Y7 HC6O8H10O1G7 ZC5U3C2Y4J3文档编码:CG8L2U6L7Y7 HC6O8H1
