derivative of 7x^2-4x

Lösung

\frac{d}{d x} (7 x^{2} - 4 x)

14 x - 4

Schritte zur Lösung

\frac{d}{d x} (7 x^{2} - 4 x)

Wende die Summen-/Differenzregel an:

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

= \frac{d}{d x} (7 x^{2}) - \frac{d}{d x} (4 x)

\frac{d}{d x} (7 x^{2}) = 14 x

\frac{d}{d x} (4 x) = 4

= 14 x - 4

d er i v a t i v e f (x) = \frac{x ^{5} - 5 x ^{2}}{2 x ^{5} + 5 x}

\frac{\partial}{\partial x} (3 x z^{3} e^{y^{2}})

\int (ln (2 x))^{2} d x

x \to - 3 lim (\frac{2}{x + 2})

\int x (x + 3) d x
