derivative of

f (x) = - 4 x^{2}

- 8 x

Solution steps

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

Take the constant out:

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

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

Apply the Power Rule:

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

= - 4 \cdot 2 x^{2 - 1}

Simplify

= - 8 x

\frac{\partial}{\partial y} (x e^{2 x - 3 y})

x \to 0 lim (\frac{sin ( 4 x ) cos ( 3 x )}{7 x})

x \to 0 lim (x^{x^{3}})

x \to 1 lim (3 x - 4)

e^{x^{4} + 9 x}
