求函数值域题型和方法
一、函数值域基本知识 1.定义:在函数 y ? f ( x) 中,与自变量 x 的值对应的因变量 y 的值叫做函数值,函数值的集合叫 做函数的值域(或函数值的集合) 。 2.确定函数的值域的原则 ①当函数 y ? f ( x) 用表格给出时,函数的值域是指表格中实数 y 的集合; ②当函数 y ? f ( x) 用图象给出时,函数的值域是指图象在 y 轴上的投影所覆盖的实数 y 的集合; ③当函数 y ? f ( x) 用解析式给出时,函数的值域由函数的定义域及其对应法则唯一确定; ④当函数 y ? f ( x) 由实际问题给出时,函数的值域由问题的实际意义确定。 二、常见函数的值域,这是求其他复杂函数值域的基础。 函数的值域取决于定义域和对应法则,不论采用什么方法球函数的值域均应考虑其定义域。 一般地,常见函数的值域: 1.一次函数 y ? kx ? b ? k ? 0? 的值域为 R. 2.二次函数 y ? ax2 ? bx ? c ? a ? 0? ,当 a ? 0 时的值域为 ?

? 4ac ? b2 ? , ?? ? ,当 a ? 0 时的值域为 ? 4a ?

? 4ac ? b2 ? ., ?? , ? 4a ? ? ?
3.反比例函数 y ? 4.指数函数 y ? a
x

k ? k ? 0 ? 的值域为 ? y ? R y ? 0? . x

? a ? 0且a ? 1? 的值域为 ? y

y ? 0? .

5.对数函数 y ? loga x ? a ? 0且a ? 1? 的值域为 R. 6.正,余弦函数的值域为 ??1,1? ,正,余切函数的值域为 R. 三、求解函数值域的 7 种题型 题型一:一次函数 y ? ax ? b ? a ? 0? 的值域(最值) 1、一次函数: y ? ax ? b ? a ? 0? 当其定义域为 R ,其值域为 R ;

大小即可。若区间的形式为 ? ??, n? 或 ? m, ??? 等时,需结合函数图像来确定函数的值域。 题型二:二次函数 f ( x) ? ax2 ? bx ? c(a ? 0) 的值域(最值)

2、一次函数 y ? ax ? b ? a ? 0? 在区间 ?m, n? 上的最值,只需分别求出 f ? m? , f ? n ? ,并比较它们的

一般情况下,都可以用判别式法求其值域。但要注意以下三个问题: ①检验二次项系数为零时,方 程是否有解,若无解或是函数无意义,都应从值域中去掉该值;②闭区间的边界值也要考查达到该值时 的 x 是否存在;③分子、分母必须是既约分式。 例 6: y ? 例 7: y ?

求原函数在区间 ? ?1, ?? ? 上的值域,即求使上述方程在 ? ?1, ?? ? 有实数解时系数 y 的取值范围 当 y ? 0 时,解得: x ? 1? ? ?1, ??? 也就是说, y ? 0 是原函数值域中的一个值 …① 当 y ? 0 时,上述方程要在区间 ? ?1, ?? ? 上有解,

? ?0 1 ? 即要满足 f ? ?1? ? 0 或 ? 2 y ? 1 解得: 0 ? y ? ……② 8 ?? 2 y ? ?1 ? ? 1? 综合①②得:原函数的值域为: ?0, ? ? 8? 题型五: 形如 y ? ax ? b ? cx ? d 的值域 这类题型都可以通过换元转化成二次函数在某区间上求值域
问题,然后求其值域。 例 10: 求函数 y ? 2x ? 4 1 ? x 在 x ? ? ?8,1? 时的值域 题型六:分段函数的值域: 一般分别求出每一分段上函数的值域, 然后将各个分段上的值域进行合并即可。 如果各个分段上的函 数图像都可以在同一坐标系上画出,从图像上便可很容易地得到函数的值域。 例 11: y ? x ?1 ? x ? 2 例 12: y ? ? x ? 4 x ? 1

??4, 4?

?3, ?? ? ? ??,5?

题型七:复合函数的值域 对于求复合函数的值域的方法是:首先求出该函数的定义域,然后在定义域的范围内由内层函数的 值域逐层向外递推。 例 13: y ? 例 14: y ?

x ?1 ? ?1 ? x ? 1? 2? x

四、函数值域求解的十六种求法 (1)直接法(俗名分析观察法) : 有的函数结构并不复杂,可以通过基本函数的值域及不等式的性质观察出函数的值域。即从自变量

x 的范围出发,推出 y ? f ( x) 的取值范围。或由函数的定义域结合图象,或直观观察,准确判断函数值
域的方法。注意此法关键是定义域。

x ? 1的值域。

x ? 1 ? x ? 1, ? x ≥1? 的值域。 x 2 ? 6 x ? 10 的值域。

(2)配方法: 二次函数或可转化为二次函数的函数常用此方法来还求解,但在转化的过程中要注意等价性,特别 是不能改变定义域。对于形如 y ? ax2 ? bx ? c ? a ? 0? 或 F ? x ? ? a ? ? f ? x ?? ? ? bf ? x ? ? c ? a ? 0 ? 类的函
2

数的值域问题,均可使用配方法。 例 1.求函数 y ?

? 2x ? x 2 ? 3 的值域。
? ( x ? 1) 2 ? 4 ,于是:

2 分析与解答:因为 ? 2 x ? x ? 3 ? 0 ,即 ? 3 ? x ? 1 , y ?

0 ? ?( x ? 1) 2 ? 4 ? 4 , 0 ? y ? 2 。

1 4 1 ? x ? 2 时,函数 y ? x ? ? 2 是单调减函数,所以 6 ? y ? 18 ; 4 x 4 4 当 2 ? x ? 4 时,函数 y ? x ? ? 2 是单调增函数,所以 6 ? y ? 7 。 x 1 1 所以函数在区间 x ? [ ,4] 的值域是 6 ? y ? 18 。 4 4
当 (3)最值法: 对于闭区间上的连续函数,利用函数的最大值、最小值,求函数的值域的方法。 例 1 求函数 y=3-2x-x2 的值域。 解:由 3-2x-x2≥0,解出定义域为[-3,1] 。 函数 y 在[-3,1]内是连续的,在定义域内由 3-2x-x2 的最大值为 4,最小值为 0。 ∴函数的值域是[0,2] 例 2:求函数 y ? 2 , x ?? ?2, 2? 的值域。

(4)反函数法(逆求或反求法) : 利用函数和它的反函数的定义域与值域的互逆关系,通过求反函数的定义域,得到原函数的值域。 即通过反解,用 y 来表示 x ,再由 x 的取值范围,通过解不等式,得出 y 的取值范围。对于形如

y?

cx ? d (a ? 0) 的值域,用函数和它的反函数定义域和值域关系,通过求反函数的定义域从而得到原函 ax ? b

数的值域。 例 1:求函数 y ?

1 ? 2x 的值域。 1 ? 2x

解:由 y ?

1? y 1 ? 2x x 解得 2 ? , x 1? y 1? 2

∵ 2 ? 0 ,∴
x

1? y ? 0 ,∴ ?1 ? y ? 1 1? y

∴函数 y ?

1 ? 2x 的值域为 y ? (?1,1) 。 1 ? 2x

(5)分离常数法: 分子、分母是一次函数得有理函数,可用分离常数法,此类问题一般也可以利用反函数法。小结: 已知分式函数 y ?

ax ? b (c ? 0) ,如果在其自然定义域(代数式自身对变量的要求)内,值域为 cx ? d

? ?y y ? ?

a? ,采用部分分式法将原函数化为 ? ;如果是条件定义域(对自变量有附加条件) c?

ad b? a c (ad ? bc) ,用复合函数法来求值域。 y? ? c cx ? d 1? x 例 1:求函数 y ? 的值域。 2x ? 5 1 7 7 ? (2 x ? 5) ? 1? x 2 ??1? 2 , 解:∵ y ? ? 2 2x ? 5 2x ? 5 2 2x ? 5 7 1 ∵ 2 ? 0 ,∴ y ? ? , 2 2x ? 5 1? x 1 ∴函数 y ? 的值域为 { y | y ? ? } 。 2x ? 5 2
(6)换元法(代数/三角) : 对于解析式中含有根式或者函数解析式较复杂的这类函数,可以考虑运用代数或三角代换,将所给 函数化成值域简单的熟悉的容易确定的基本函数,从而求得原函数的值域。当根式里是一次式时,用代 数换元;当根式里是二次式时,用三角换元。 对形如 y ?

2

2 ? ?x ? 5? ,令 x ? 5 ? 2 cos? ,
2

因为 2 ? ?x ? 5? ? 0 ? 2 ? 2 cos2 ? ? 0 ? ?1 ? cos? ? 1 , ? ? [0, ? ] ,则

2 ? ?x ? 5? = 2 sin ? ,
2

于是 y ?

? ? 5? ?? ? 2 sin ? ? 2 cos? ? 5 ? 2 sin?? ? ? ? 5 , ? ? ? [ , ] , 4 4 4 4? ?

?

2 ?? ? ? sin?? ? ? ? 1,所以 5 ? 2 ? y ? 7 。 2 4? ? a1 x 2 ? b1 x ? c1 ( a1 , a2 不同时为 0 )的函数常采用此法, a2 x 2 ? b2 x ? c2

(7)判别式法:根判别式法:对于形如 y ?

就是把函数转化成关于 x 的一元二次方程(二次项系数不为 0 时) ,通过方程有实数根,从而根的判别式 大于等于零,求得原函数的值域. 对二次函数或者分式函数(分子或分母中有一个是二次)都可通用,但这类题型有时也可以用其他方法 进行化简 如:

但此时的函数的定义域由 x (2 ? x ) ? 0 ,得 0 ? x ? 2
2 2 由 ? ? 0 ,仅保证关于 x 的方程: 2x ? 2( y ? 1)x ? y ? 0 在实数集 R 有实根,而不能确保其实根在区间

[0,2]上,即不能确保方程(1)有实根,由 ? ? 0 求出的范围可能比 y 的实际范围大,故不能确定此

?1 3? ?2 , 2? ?。 函数的值域为 ?
可以采取如下方法进一步确定原函数的值域。 ∵0 ? x ? 2

? y ? x ? x(2 ? x) ? 0

? y min ? 0, y ? 1 ? 2 代入方程(1)
x1 ?
解得:

2 ? 2 ? 24 2 2

?[0,2]

即当

x1 ?

2 ? 2 ? 24 2 2 时,

原函数的值域为: [0,1 ? 2 ] 注:由判别式法来判断函数的值域时,若原函数的定义域不是实数集时,应综合函数的定义域,将扩大 的部分剔除。 (8)函数导数与单调性法: 1)确定函数在定义域(或某个定义域的子集)上的单调性,求出函数的值域。例如,

f ? x ? ? ax ?

b ? a ? 0, b ? 0 ? .当利用不等式法等号不能成立时,可考虑利用函数的单调性解题。 x

例 1:求函数 y ? x ? 1 ? 2x 的值域。 解:∵当 x 增大时, 1 ? 2 x 随 x 的增大而减少, ? 1 ? 2 x 随 x 的增大而增大, ∴函数 y ? x ? 1 ? 2x 在定义域 (??, ] 上是增函数。 ∴y?

∴函数 y ? x ? 1 ? 2x 的值域为 (??, ] 。 2)若函数 f 在 ( a, b) 内可导, 可以利用导数求得 f 在 ( a, b) 内的极值, 然后再计算 f 在 a , b 点的极 限值. 从而求得 f 的值域.

例: 求函数 f ( x) ? x 3 ? 3x 在 (?5,1) 内的值域. 分析:显然 f 在 (?5,3) 可导,且 f ?( x) ? 3x 2 ? 3 . 由 f ?( x) ? 0 得 f 的极值点为 x ? 1, x ? ?1 .

f (?1) ? 2,

f (1 ? 0) ? ?2 . f (?5 ? 0) ? 140.

所以, 函数 f 的值域为 (?2,140) . 例 3:求函数 f ?x? ? 1 ? x ? 1 ? x 的值域。 分析与解答:因为 ?

?1 ? x ? 0 ? ?1 ? x ? 1 ,而 1 ? x 与 1 ? x 在定义域内的单调性不一致。现构 ?1 ? x ? 0

造 相 关 函 数 g ?x? ? 1 ? x ? 1 ? x , 易 知 g ( x) 在 定 义 域 内 单 调 增 。 g max ? g ?1? ?

(9)基本不等式法 利用基本不等式求函数值域, 其题型特征解析式是和式时要求积为定值,解析式是积时要求和为定 值。 利用基本不等式 a ? b ? 2 ab ,用此法求函数值域时,要注意条件“一正,二定,三相等”.如利用

a ? b ? 2 ab 求某些函数值域(或最值)时应满足三个条件① a ? 0, b ? 0 ;② a ? b ?或ab ? 为定值;③
取等号成立的条件 a ? b .三个条件缺一不可。此外,有时需要合理地添项和拆项和两边平方等技巧, 添 项和拆项的原则是要使最终的乘积结果中不含自变量,比如求函数 y ? x ? 例 1 求函数 解:

k (k ? 0, n ? N ) 的值域。 xn

y?
?

x?2 x ?1 的值域.

y?

x?2 x ?1

x ?1 ?

1 x ?1

? 2 , 当且仅当 x ? 1 时 " ?" 成立. 故函数的值域为 y ? [2,??) .

此法可以灵活运用 , 对于分母为一次多项式的二次分式, 当然可以运用判别式法求得其值域 , 但是 若能变通地运用此法, 可以省去判别式法中介二次不等式的过程. 例 2:求函数的值域: y ?

2 x2 ? x ? 1 ? 1? ? x ? ?. 2x ?1 ? 2?

1 2 x 2 ? x ? 1 x ? 2 x ? 1? ? 1 1 1 1 解: y ? ? ? x? ? x? ? 2 ? 2 x ?1 2 x ?1 2 x ?1 2 x?1 2 2

?? 2 x ? 1( x ? ?1) ? y ? ?3( ?1 ? x ? 2) ,画出它的图象,由图象可知,函数的值域是{y|y ? 3}。 ?2 x ? 1( x ? 2) ?
解法 2(几何法或图象法) :∵函数 y=|x+1|+|x-2|表示数轴上的动点 x 到两定点-1,2 的距离之和,∴ 易见 y 的最小值是 3,∴函数的值域是[3,+ ? ]。如图
x -1 O 1 2

-1 O 1 2x



例 2.求函数 y ?

x2 ? 4 x ? 5 ? x2 ? 4 x ? 8 的值域。

点拨:将原函数变形,构造平面图形,由几何知识,确定出函数的值域。 解:原函数变形为 f ( x) ?

( x ? 2) 2 ? 1 ? ( x ? 2) 2 ? 22

作一个长为 4、宽为 3 的矩形 ABCD,再切割成 12 个单位正方形。设 HK= x ,则
2 2 EK=2 ?x ,KF=2 ? x ,AK= ( x ? 2) ? 2 , 2 KC= ( x ? 2) ? 1 。

由 三 角 形 三 边 关 系 知 , AK+KC≥AC=5。当 A、K、C 三点共线时 ∴原函数的知域为{y|y≥5} 。 例 3. 求函数 y ? 1 ? x ? 1 ? x 的值域。

取等号。

2 2 解析:令 u ? 1 ? x , v ? 1 ? x ,则 u ? 0, v ? 0 , u ? v ? 2 , u ? v ? y ,原问题转化为:当
2 2 直线 u ? v ? y 与圆 u ? v ? 2 在直角坐标系 uov的第一象限有公共点时,求直线的截距的取值范围。

由图 1 知:当 u ? v ? y 经过点 (0, 2 ) 时, y min ? 当直线与圆相切时, y max ? OD ? 所以,值域为 2 ? y ? 2

x2 ? 6 x+13 ? x2 ? 4 x+5 的值域。
( x ? 3) 2 ? (0 ? 2) 2 ? ( x ? 2) 2 ? (0 ? 1) 2

解:将函数变形为 y ?

上式可看成定点 A ( 3 , 2)到点 P ( x , 0 )的距离与定点 B(?2,1) 到点 P ( x , 0) 的距离之差。即

y ? AP ? BP
由图可知: (1)当点 P 在 x 轴上且不是直线 AB 与 x 轴的交点时,如点 P? ,则构成 ?ABP ? ,根据三 角形两边之差小于第三边,有 AP ? BP ? AB ?
