derivative of f(x)=e^{-x+1}x-2e^{-x+1}

Solution

derivative of

f (x) = e^{- x + 1} x - 2 e^{- x + 1}

Solution

- e^{- x + 1} x + 3 e^{- x + 1}

Solution steps

\frac{d}{d x} (e^{- x + 1} x - 2 e^{- x + 1})

Apply the Sum/Difference Rule:

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

= \frac{d}{d x} (e^{- x + 1} x) - \frac{d}{d x} (2 e^{- x + 1})

\frac{d}{d x} (e^{- x + 1} x) = - e^{- x + 1} x + e^{- x + 1}

\frac{d}{d x} (2 e^{- x + 1}) = - 2 e^{- x + 1}

= - e^{- x + 1} x + e^{- x + 1} - (- 2 e^{- x + 1})

Simplify

= - e^{- x + 1} x + 3 e^{- x + 1}
