derivative of

y = - 2 x - 1

- 2

Solution steps

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

Apply the Sum/Difference Rule:

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

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

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

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

= - 2 - 0

Simplify

= - 2

n = 1 \sum \infty \frac{1}{n + 3 ^{n}}

\frac{d}{d x} (\frac{e ^{x} + 1}{e ^{x} - 1})

f (x) = 9 x^{8} e^{x} + e^{x} x^{9}

\frac{d}{d x} (\frac{5 + csc ( x )}{9 - csc ( x )})

y^{^{'}} = x^{4} - \frac{1}{x} y
