\frac{d}{d x} (20 e^{- x})

- 20 e^{- x}

Solution steps

\frac{d}{d x} (20 e^{- x})

Take the constant out:

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

= 20 \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

= 20 e^{- x} (- 1)

Simplify

= - 20 e^{- x}

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

y^{^{'}} + 35 y = 7

- 2 t^{2} - 8 t + 9

x \to 6 - lim (\frac{x - 6}{∣ x - 6 ∣})

\frac{d}{d x} (ln (x^{x}))
