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

\int \frac{x}{1 - 5 x ^{2}} d x

\frac{d}{d x} (\frac{1}{x ^{13}})

\int 4 tan^{3} (x) sec (x) d x

\int_{- 1}^{0} (x + 1)^{3} d x

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