答案
变形得:(x-1)(x-4)<0,
解得:1<x<4,
∴B={2,3},
∵A={1,2},
∴A∪B={1,2,3},
∵集合U={0,1,2,3,4,5},
∴∁∪(A∪B)={0,4,5}.
故答案为:{0,4,5}
核心考点
举一反三
A.{0,1} | B.{1} | C.{0,1,2} | D.ϕ |
题型:2x+1|>3},则M∩N=( )
A.(-3,-2]∪[1,2] | B.[-3,-2)∪(1,2] | C.(-3,-2)∪(1,+∞) | D.(-∞,-3)∪(1,2] |
A.{-1,-2,-3} | B.{0,1,2,3} | C.{2,3} | D.{0,-1,-2,-3} |
