A) \[[-1,3]\]
B) \[[0,2]\]
C) \[[-1,1]\]
D) None of these
Correct Answer: A
Solution :
[a] \[\left| \left| x-1 \right|-1 \right|\le 1\Rightarrow -1\le \left| x-1 \right|-1\le 1\] \[\Rightarrow 0\le \left| x-1 \right|\le 2\Rightarrow -2\le x-1\le 2\] \[\Rightarrow -1\le x\le 3\Rightarrow x\in [-1,3]\]You need to login to perform this action.
