\frac{d}{d x} (- 4 e^{- 2 x})

8 e^{- 2 x}

Solution steps

\frac{d}{d x} (- 4 e^{- 2 x})

Take the constant out:

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

= - 4 \frac{d}{d x} (e^{- 2 x})

Apply the chain rule:

e^{- 2 x} \frac{d}{d x} (- 2 x)

= e^{- 2 x} \frac{d}{d x} (- 2 x)

\frac{d}{d x} (- 2 x) = - 2

= - 4 e^{- 2 x} (- 2)

Simplify

= 8 e^{- 2 x}
