derivative of

9 x + 4

\frac{9}{2 9 x + 4}

Solution steps

\frac{d}{d x} (9 x + 4)

Apply the chain rule:

\frac{1}{2 9 x + 4} \frac{d}{d x} (9 x + 4)

= \frac{1}{2 9 x + 4} \frac{d}{d x} (9 x + 4)

\frac{d}{d x} (9 x + 4) = 9

= \frac{1}{2 9 x + 4} \cdot 9

Simplify

\frac{1}{2 9 x + 4} \cdot 9 : \frac{9}{2 9 x + 4}

= \frac{9}{2 9 x + 4}

x \to - 6 - lim (\frac{- 9 x}{x + 6})

\int_{- \infty}^{0} e^{3 x} d x

\int \frac{1}{u - 1} d u

\int_{10}^{5} 3 x d x

(- 6, 9), (7, - 9)
