A) \[[-2,0]\cup [2,4]\]
B) \[(-2,0)\cup (2,4)\]
C) \[[-2,0]\cup [1,3]\]
D) \[[-2,0]\cup [1,3]\]
Correct Answer: A
Solution :
\[f(x)\] is defined for \[-1\le |x-1|-2\le 1\] \[\Rightarrow \] \[1\le |x-1|\le 3\] \[\Rightarrow \] \[1\le (x-1)\le 3\]or \[-3\le x-1\le -1\] \[\Rightarrow \] \[2\le x\le 4\] or \[-2\le x\le 0\] \[\Rightarrow \] \[x\in [2,4]\cup [-2,0]\]You need to login to perform this action.
