1、高中数学集合检测题一、选择题：在每小题给出的四个选项中，只有一项是符合题目要求的.1.已知集合 m = -1,1, -2, 2, n = y | y = x, x m ,则 m n 是 m 1,41 f2. 设全集 u=r，集合 a = x | x2 1，则cua =a. 1b. 1，1c. 1d. -1,13. 已知集合 u=x | x 0 ， cu a = x | 0 x 2 ，那么集合 a =a. x | x 0或x 2 b. x | x 2c. x | x 2d. x | x 24. 设全集 i = 0, -1, -2, -3, -4,集合 m = 0, -1, -2, n = 0,

2、-3, -4，则(i m )i n =ab -3, -4c-1, -2d 5. 已知集合m=x n|4-x n，则集合 m 中元素个数是a3b4c5d66. 已知集合 a = -1,0,1，则如下关系式正确的是a a ab 0ac 0 ad a7.集合 a = x - 2 x 2 ， b = x - 1 x 3 ,那么 a b =a.x - 2 x 3b.x1 x 2c.x - 2 x 1d.x 2 x a，若m i n ，则有a.a -1c.a -1d.a -112、已知全集u = 0,1, 2, 4, 6,8,10, a = 2, 4, 6, b = 1,则(cu a) b = 0,1,8

3、,10 1,2, 4,60,8,10 f选择题答案题号123456789101112答案二、填空题：13设 u三角形，a锐角三角形，则cu a .14. 已知 a=0，2，4，cua=-1，1，cub=-1，0，2，求 b=。15、已知全集u = 2,4, a2 - a +1, a = a +1, 2,c ua = 7则a = 16 集合 a = 0,2, 4, 6,cu a = -1,-3,1,3,cu b = -1,0, 2则集合 。17、已知全集 ur，集合 ax12x19，则 c u a 王新敞18.设全集 a = x x a, b = x - 1 x 3,且a (cr b) = r

4、,则实数 a 的取值范围是 三、解答题：解答应写出文字说明，证明过程或演算步骤.19若 a=3,5, b = x | x2 + mx + n = 0, a u b = a , a i b = 5 ,求 m、n 的值。20已知集合 a = x | x2 - 3x + 2 = 0， b = x x 2 - mx + m - 1 = 0 .若a u b = a ，求实数 m 的取值范围。21 已知集合 a = x | a -1 x 2a +1 ， b = x | 0 x 1，若 a i b = ，求实数 a 的取值范围。22设 a = x | x2 - ax + a2 -19 = 0， b = x

5、| x2 - 5x + 6 = 0， 若 a i b = a u b ，求 a 的值。23. 若集合 a = - 4,2a - 1, a 2 ， b = a - 5,1 - a,9,且 a i b = 9，求a 的值。答案15adcbc 610dacdd1112aa“”“”at the end, xiao bian gives you a passage. minand once said, people who learn to learn are very happy people. in every wonderful life, learning is an eternal theme

6、. as a professional clerical and teaching position, i understand the importance of continuous learning, life is diligent, nothing can be gained, only continuous learning can achieve better self. only by constantly learning and mastering the latest relevant knowledge, can employees from all walks of life keep up with the pace of enterprise development and innovate to meet the needs of the market. this document is also edited by my stud
