A) {0, 1}
B) {?1, 1}
C) R
D) \[R-\{-2\}\]
Correct Answer: B
Solution :
\[f(x)=\frac{x+2}{|x+2|}\] \[f(x)=\left\{ \begin{matrix} -1, \\ \,\,1, \\ \end{matrix} \right.\,\,\,\,\,\,\begin{matrix} x<-2 \\ x>-2 \\ \end{matrix}\] \ Range of \[f(x)\] is \[\{-1,\,1\}\].You need to login to perform this action.
