已知集合A={m|(m-2)(m^2+1)>0},集合B={m|f(x)=log2[4x^2+4(m-2)x+1]的定义域为R

已知集合A={m|(m-2)(m^2+1)>0},集合B={m|f(x)=log2[4x^2+4(m-2)x+1]的定义域为R

已知集合A={m|(m-2)(m^2+1)>0}, A={m|m>2}
集合B={m|f(x)=log2[4x^2+4(m-2)x+1]的定义域为R
判别式=16(m^2-4m+4)-16<0
m^2-4m+3<0 1B={m|1A∩B={m|21，若集合C包含于A∩B且C=[m,m+1/2]，
m>2
m+1/2<3 m<2.5
m的取值范围 2
2，设全集U={m|m＞3/2}，求A∩CUB
C(UB)={m|m>=3}
A={m|m>2}
