derivative of-x^3+2x^2-x

解

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

解

- 3 x^{2} + 4 x - 1

解答ステップ

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

和/差の法則を適用:

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

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

\frac{d}{d x} (x^{3}) = 3 x^{2}

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

\frac{d x}{d x} = 1

= - 3 x^{2} + 4 x - 1
