Let ( A = x: x R ,|x| < 1 ); ( B = x: x R ,|x-1| 1 and A B = R - D , ) then the set ( D ) is
Options
- A( x: 1 < x 2 )
- B( x: 1 x < 2 )
- C( x: 1 x 2 )
- DNone of these
Correct answer
B. ( x: 1 x < 2 )
Step-by-step solution
( aligned & A =[x: x R ,-1 < x < 1] & B =[x: x R : x-1 -1 or x-1 1] &=[x: x R: x 0 or x 2] & A B=R-D, aligned ) where (D=[x: x R, 1 x < 2] )
