derivative of

f (x) = 2 x + 4

\frac{1}{2 x + 4}

Solution steps

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

Apply the chain rule:

\frac{1}{2 2 x + 4} \frac{d}{d x} (2 x + 4)

= \frac{1}{2 2 x + 4} \frac{d}{d x} (2 x + 4)

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

= \frac{1}{2 2 x + 4} \cdot 2

Simplify

\frac{1}{2 2 x + 4} \cdot 2 : \frac{1}{2 x + 4}

= \frac{1}{2 x + 4}

\int 2 x (x^{2} + 9)^{7} d x

\int \frac{5}{9 x ^{2} - 16} d x

f (x) = 6 x^{3} + 7

\int 6 e^{6 x} sin (e^{6 x}) d x

\int \frac{1}{4 y ^{2}} d y
