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

- x^{2}

Solution steps

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

Take the constant out:

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

= - \frac{1}{3} \frac{d}{d x} (x^{3})

Apply the Power Rule:

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

= - \frac{1}{3} \cdot 3 x^{3 - 1}

Simplify

- \frac{1}{3} \cdot 3 x^{3 - 1} : - x^{2}

= - x^{2}
