函数y=√log1/2(x^2-1)的定义域是多少?A.[-√2,-1)U(1,√2] B.(-√3,-1)U(1,√2) C.[-√2,-1)U(1,2) D.(-2.,-1)U(1,2)
函数y=√log1/2(x^2-1)的定义域是多少?
A.[-√2,-1)U(1,√2] B.(-√3,-1)U(1,√2) C.[-√2,-1)U(1,2) D.(-2.,-1)U(1,2)

函数y=√log1/2(x^2-1)的定义域是多少?A.[-√2,-1)U(1,√2] B.(-√3,-1)U(1,√2) C.[-√2,-1)U(1,2) D.(-2.,-1)U(1,2)
1.函数y=√[log1/2(x-1)]的定义域 log(1/2)(x-1)=-log2(x-1)---》x-1>0-->x>1 -log2(x-1)>0,log2(x-1)

很明显是A
