derivative of

9 - x

- \frac{1}{2 9 - x}

Solution steps

\frac{d}{d x} (9 - x)

Apply the chain rule:

\frac{1}{2 9 - x} \frac{d}{d x} (9 - x)

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

\frac{d}{d x} (9 - x) = - 1

= \frac{1}{2 9 - x} (- 1)

Simplify

= - \frac{1}{2 9 - x}

f (x) = (\frac{4 x}{7 x + 5})^{4}

y^{^{''}} + y^{^{'}} = 0, y (0) = 2, y^{^{'}} (0) = 1

x \cdot \frac{d y}{d x} = y^{2} - y

(x^{2} + 3 x - 1) e^{x}

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