derivative of

f (x) = \frac{x}{x + 2}

\frac{x + 4}{2 ( x + 2 ) ^{2}}

Solution steps

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

Apply the Quotient Rule:

(\frac{f}{g})^{'} = \frac{f ^{'} \cdot g - g ^{'} \cdot f}{g ^{2}}

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

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

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

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

Simplify

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

= \frac{x + 4}{2 ( x + 2 ) ^{2}}

\frac{d}{d x} (12 e^{3 x})

x \to \infty lim (x - 2 x)

\int \frac{2 x - 1}{4 x ^{2} + 1} d x
