A) R
B) -1,1
C) R- {0}
D) [-1, 1]
Correct Answer: B
Solution :
\[f(x)=\frac{x}{1+\left| x \right|},x\in R\] If\[x>0,|x|=x\Rightarrow f(x)=\frac{x}{1+x}\]which is not defined for \[x=-1\] Thus f(x) defined for all values of R except 1and- 1 Hence, range =(-1,1).You need to login to perform this action.
