derivative of

f (x) = x^{3} + 5 x + 7

3 x^{2} + 5

Solution steps

\frac{d}{d x} (x^{3} + 5 x + 7)

Apply the Sum/Difference Rule:

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

= \frac{d}{d x} (x^{3}) + \frac{d}{d x} (5 x) + \frac{d}{d x} (7)

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

\frac{d}{d x} (5 x) = 5

\frac{d}{d x} (7) = 0

= 3 x^{2} + 5 + 0

Simplify

= 3 x^{2} + 5

\frac{4}{s ^{2} + 2 s + 4}

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

\frac{\partial}{\partial s} (- (s^{2} + t^{2}))

\int_{1}^{e} ln (13 x) d x

\int e^{1 - 8 t} d t
