A) R
B) \[R-\{1\}\]
C) \[R-\{-1\}\]
D) \[R-\{0\}\]
Correct Answer: B
Solution :
Given, \[f(x)=\left| x-1 \right|{{e}^{x}}\] Since, \[\left| x-1 \right|\] is not differentiable at \[x=1\] So, \[f(x)=\left| x-1 \right|{{e}^{x}}\] is not differentiable at \[x=1\]. Hence, the required set is \[R-\{1\}.\]You need to login to perform this action.
