A) \[{{e}^{x}}\]
B) \[x{{e}^{x}}+{{e}^{x}}\]
C) \[x{{e}^{x}}-{{e}^{x}}\]
D) \[x{{e}^{x}}\]
Correct Answer: B
Solution :
\[\int\limits_{0}^{x}{f(x)dx=x{{e}^{x}}}\] \[\Rightarrow \] \[f(x)=\frac{d}{dx}(x{{e}^{x}})\] \[\Rightarrow \] \[f(x)=x{{e}^{x}}+{{e}^{x}}\]You need to login to perform this action.
