A) \[(1,\infty )\]
B) \[\left( \frac{1}{e},\infty \right)\]
C) \[[e,\infty )\]
D) \[(0,1)\cup (1,\infty )\]
Correct Answer: D
Solution :
\[f(x)=x\ln x-x+1;f(1)=0\] \[f'(x)=1+\ln x-1=\ln x\]\[f'(x)=\] \[\Rightarrow \]f (x) is decreasing for (0,1) and increasing for \[(1,\infty )\]You need to login to perform this action.
