derivative of

f (x) = \frac{7}{x}

- \frac{7}{x ^{2}}

Solution steps

\frac{d}{d x} (\frac{7}{x})

Take the constant out:

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

= 7 \frac{d}{d x} (\frac{1}{x})

Apply exponent rule:

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

= 7 \frac{d}{d x} (x^{- 1})

Apply the Power Rule:

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

= 7 (- 1 \cdot x^{- 1 - 1})

Simplify

7 (- 1 \cdot x^{- 1 - 1}) : - \frac{7}{x ^{2}}

= - \frac{7}{x ^{2}}

x \to \infty lim ((\frac{x - 3}{x - 4})^{- x})

\frac{d}{d x} (ln (sinh (5 x)))

y = (3 x - 2 x^{2})^{3}

\frac{9 + 6 x}{7 - 4 x}

y = e^{x} (p + p p)
