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

e^{- x} x - 2 e^{- x}

Solution steps

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

Apply the Sum/Difference Rule:

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

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

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

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

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

Simplify

= e^{- x} x - 2 e^{- x}

y^{^{'}} = y^{2} - 100

x \to - 2 lim (- 4 x + a)

\frac{d}{d b} (\frac{T}{- ln ( \frac{b}{a} )})

\frac{d}{d x} (x^{3} - 4 x^{2} + 1)

\frac{\partial}{\partial y} (2 y^{2} e^{x y^{2}})
