derivative of

2 x^{2} - 4 x - 1

4 x - 4

Solution steps

\frac{d}{d x} (2 x^{2} - 4 x - 1)

Apply the Sum/Difference Rule:

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

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

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

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

\frac{d}{d x} (1) = 0

= 4 x - 4 - 0

Simplify

= 4 x - 4

\frac{d}{d x} (e^{∣ x ∣})

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

y = (x^{3} - 9 x)^{8}, (3, 0)

x^{2} y^{^{''}} - 2 x y^{^{'}} + 2 y = x^{2} + 2

\frac{d}{d x} (\frac{0.9 e ^{x}}{tan ( x )})
