已知集合M={x|(x-1)2<4,x∈R},N={x|-2<x≤3,x∈Z},则M∩N=( )A.{0,1,2} | B.{-1,0,1,2} | C.{-1,0,2,3} | D.{0,1,2,3} |
|
答案
由M={x|(x-1)2<4,x∈R}={x|-1<x<3}, N={x|-2<x≤3,x∈Z}={-1,0,1,2,3}, 则M∩N={0,1,2}. 故选A. |
举一反三
已知集合M={y|y=2x,x>0},N={y|y=},则M∩N等于( )A.∅ | B.{1} | C.{y|y>1} | D.{y|y≥1} |
|
已知集合M={x|x<3},N={x|2x>},则M∩N等于______. |
已知集合A={x|x<-1或x>1},B={x|x>1},则A∩B=( )A.{x|x>1} | B.{x|x>0} | C.{x|x<-1} | D.{x|x<-1或x>1} |
|
集合A={x|≥1},B={y|y=asinθ,θ∈[-,],a>0} (1)求集合A和B; (2)若A∩B=∅,求a的取值范围. |
若集合A={-2,-1,0,1,2},则集合{y|y=|x+1|,x∈A}=( )A.{1,2,3} | B.{0,1,2} | C.{0,1,2,3} | D.{-1,0,1,2,3} |
