f (x) = \frac{1}{5 x - 7}

- \frac{5}{( 5 x - 7 ) ^{2}}

Schritte zur Lösung

\frac{d}{d x} (\frac{1}{5 x - 7})

Wende Exponentenregel an:

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

= \frac{d}{d x} ((5 x - 7)^{- 1})

Wende die Kettenregel an:

- \frac{1}{( 5 x - 7 ) ^{2}} \frac{d}{d x} (5 x - 7)

= - \frac{1}{( 5 x - 7 ) ^{2}} \frac{d}{d x} (5 x - 7)

\frac{d}{d x} (5 x - 7) = 5

= - \frac{1}{( 5 x - 7 ) ^{2}} \cdot 5

Vereinfache

- \frac{1}{( 5 x - 7 ) ^{2}} \cdot 5 : - \frac{5}{( 5 x - 7 ) ^{2}}

= - \frac{5}{( 5 x - 7 ) ^{2}}

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