A) \[\{x\in R:0\le x\le 1\}\]
B) \[(0,1)\]
C) \[\{x\in R:x>0\}\]
D) \[\{x\in R:x\le 0\}\]
Correct Answer: B
Solution :
Given, \[f(x)=[2x]-2[x],\forall \,x\in R\] Let \[x\]is an integer, then \[f(x)=0\] and let \[x\]is not an integer, then \[f(x)=1\] \[\therefore \] Range of \[f(x)=\{0,1\}\]You need to login to perform this action.
