derivative of

f (x) = - 9 x^{2}

- 18 x

Solution steps

\frac{d}{d x} (- 9 x^{2})

Take the constant out:

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

= - 9 \frac{d}{d x} (x^{2})

Apply the Power Rule:

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

= - 9 \cdot 2 x^{2 - 1}

Simplify

= - 18 x

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

\frac{d}{d x} (\frac{x ^{5}}{6})

sin (\frac{π x}{6})

\frac{d y}{d x} = 3

f (x) = \frac{- x ^{2} - 9}{( x ^{2} - 9 ) ^{2}}
