derivative of

- e^{- x}

e^{- x}

Solution steps

\frac{d}{d x} (- e^{- x})

Take the constant out:

(a \cdot f)^{'} = a \cdot f^{'}

= - \frac{d}{d x} (e^{- x})

Apply the chain rule:

e^{- x} \frac{d}{d x} (- x)

= e^{- x} \frac{d}{d x} (- x)

\frac{d}{d x} (- x) = - 1

= - e^{- x} (- 1)

Simplify

= e^{- x}
