Function Expression :
\[f(x)=\frac{x}{e^{x-1}} \]Domain
\[]-\infty ;+\infty [ \]Limits
\[\lim_{x \rightarrow-\infty}f(x) = -\infty \]\[\lim_{x \rightarrow+\infty}f(x) = 0 \]
\[ \]
Derivate
\[f^{\,\prime}(x)=- x e^{2 - 2 x} e^{x - 1} + \frac{1}{e^{x - 1}} \]\[f^{\,\prime}(x)=\left(1 - x\right) e^{1 - x} \]
\[ \]
