derivative of

f (x) = - \frac{5}{x ^{4}}

\frac{20}{x ^{5}}

Solution steps

\frac{d}{d x} (- \frac{5}{x ^{4}})

Take the constant out:

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

= - 5 \frac{d}{d x} (\frac{1}{x ^{4}})

Apply exponent rule:

\frac{1}{a} = a^{- 1}

= - 5 \frac{d}{d x} (x^{- 4})

Apply the Power Rule:

\frac{d}{d x} (x^{a}) = a \cdot x^{a - 1}

= - 5 (- 4 x^{- 4 - 1})

Simplify

- 5 (- 4 x^{- 4 - 1}) : \frac{20}{x ^{5}}

= \frac{20}{x ^{5}}

x = 8

x^{2} + x

y = x + 2

(5, 2), (3, - 1)

- 3.5
