derivative of

f (x) = x^{2} - 4 x - 9

2 x - 4

Solution steps

\frac{d}{d x} (x^{2} - 4 x - 9)

Apply the Sum/Difference Rule:

(f \pm g)^{'} = f^{'} \pm g^{'}

= \frac{d}{d x} (x^{2}) - \frac{d}{d x} (4 x) - \frac{d}{d x} (9)

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

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

\frac{d}{d x} (9) = 0

= 2 x - 4 - 0

Simplify

= 2 x - 4

2 \frac{d ^{2} y}{d x ^{2}} - 6 \frac{d y}{d x} + 4 y = 2 sin (4 x)

\frac{\partial}{\partial x} (arctan (2 x + y))

y (1 + x^{2}) y^{^{'}} - x (4 + y^{2}) = 0

\int 9 sin^{3} (x) cos^{2} (x) d x

y^{^{'}} = \frac{2 x y ^{3}}{1 - x ^{2} y ^{2}}
