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

- 27 x

Solution steps

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

Take the constant out:

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

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

Apply the Power Rule:

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

= - 72 x^{2 - 1}

Simplify

= - 27 x

f (x) = (3 x - 1) (x + 2)

f (x) = 6 x^{3}

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

x \to 5 lim (- 12 x + 7)

y = \frac{3}{x + 1}, (2, 1)
