derivative of

- 4 x^{5} + 6 x^{7}

- 20 x^{4} + 42 x^{6}

Solution steps

\frac{d}{d x} (- 4 x^{5} + 6 x^{7})

Apply the Sum/Difference Rule:

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

= - \frac{d}{d x} (4 x^{5}) + \frac{d}{d x} (6 x^{7})

\frac{d}{d x} (4 x^{5}) = 20 x^{4}

\frac{d}{d x} (6 x^{7}) = 42 x^{6}

= - 20 x^{4} + 42 x^{6}

x \to + 0 lim (\frac{e ^{x} - 1}{5 x})

\int \frac{10 x ^{2} - 9 x + 8}{x ^{3} + 4 x} d x

f (x) = 19 x - 1.86 x^{2}, at x = 1

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

f (x) = \frac{2 x}{x + 1}, at x = 1
