derivative of

f (x) = 4 x - x

\frac{2}{x} - 1

Solution steps

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

Apply the Sum/Difference Rule:

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

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

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

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

= \frac{2}{x} - 1

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

x \to \infty lim (x - 5)

e^{- x} 0.25

f (x) = 1 - 2 x^{2}, - 7, at x = 2
