derivative of

f (x) = ∣ x - 4 ∣

\frac{x - 4}{∣ x - 4 ∣}

Solution steps

\frac{d}{d x} (∣ x - 4 ∣)

Apply the chain rule:

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

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

\frac{d}{d x} (x - 4) = 1

= \frac{x - 4}{∣ ( x - 4 ) ∣} \cdot 1

Simplify

= \frac{x - 4}{∣ x - 4 ∣}

\frac{d}{d x} (\frac{1}{( 3 x ^{3} + 5 x + 4 ) ^{\frac{3}{4}}})

\frac{d}{d x} ((f (x) (6 x))^{2} + 3)

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

\frac{\partial}{\partial x} (x^{2} y + 3 x y^{4})

x \to 0 lim (\frac{x}{e ^{- 3 x} - 1})
