设全集U={x∈N*|x<8},A={1,3,5,7},B={2,4,5},则CU(A∪B)=______. |
答案
∵A={1,3,5,7},B={2,4,5}, ∴A∪B={1,2,3,4,5,7}, 又全集U={1,2,3,4,5,6,7}, 则CU(A∪B)={6}. 故答案为:{6} |
举一反三
已知函数y=的定义域为集合A,B={x|2<x<9}. (1)分别求:∁R(A∩B),(∁RB)∪A; (2)已知C={x|a<x<a+3},若C⊆B,求实数a的取值范围. |
已知全集U=R,集合P={x|x2≥9},Q={x|x>2},则Q∩CUP=( )A.{x|x≥3} | B.{x|x≤-3} | C.{x|2<x<3} | D.{x|2<x≤3} |

设全集U={-,5,-3},集合A={x|3x2+px-5=0}与集合B={x|3x2+10x+q=0},且A∩B={-},求CUA,CUB. |
已知集M={0,1,2},N={2,3},则M∩N=( )A.{2} | B.{3} | C.{2,3,4} | D.{0,1,2,3,4} |
|
集合A={(x,y)|y=x2+1},B={y|y=x+1},则A∩B=( )A.[1,+∞) | B.{1} | C.{(0,1),(1,2)} | D.∅ |
