\frac{d}{d x} (- (\frac{x ^{3} + x - 1}{2}))

- \frac{1}{2} (3 x^{2} + 1)

Solution steps

\frac{d}{d x} (- (\frac{x ^{3} + x - 1}{2}))

Take the constant out:

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

= - \frac{1}{2} \frac{d}{d x} (x^{3} + x - 1)

Apply the Sum/Difference Rule:

(f \pm g)^{'} = f^{'} \pm g^{'}

= - \frac{1}{2} (\frac{d}{d x} (x^{3}) + \frac{d x}{d x} - \frac{d}{d x} (1))

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

\frac{d x}{d x} = 1

\frac{d}{d x} (1) = 0

= - \frac{1}{2} (3 x^{2} + 1 - 0)

Simplify

= - \frac{1}{2} (3 x^{2} + 1)

f (x) = \frac{7}{x} - x

\frac{d}{d x} (1 + 2 x)

\frac{\partial}{\partial x} (lo g_{10} (x))

(\frac{5 x - 1}{4 x + 2})^{- 5}

x \to 0 - lim (1 - e^{x})
