\frac{d}{d x} (7 e^{- x} + e^{4 x})

- 7 e^{- x} + e^{4 x} \cdot 4

Solution steps

\frac{d}{d x} (7 e^{- x} + e^{4 x})

Apply the Sum/Difference Rule:

(f \pm g)^{'} = f^{'} \pm g^{'}

= \frac{d}{d x} (7 e^{- x}) + \frac{d}{d x} (e^{4 x})

\frac{d}{d x} (7 e^{- x}) = - 7 e^{- x}

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

= - 7 e^{- x} + e^{4 x} \cdot 4
