derivative of 7x-1

\frac{d}{d x} (7 x - 1)

7

Solution steps

\frac{d}{d x} (7 x - 1)

Apply the Sum/Difference Rule:

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

= \frac{d}{d x} (7 x) - \frac{d}{d x} (1)

\frac{d}{d x} (7 x) = 7

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

= 7 - 0

Simplify

= 7

\frac{d}{d x} (x (x - a) ln (x + 1 + b^{2}))

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

\int \frac{x ^{n}}{n !} d x

\frac{d y}{d t} - \frac{y}{2 t} = 3 t

x \to 0 lim (ln (x^{2}) - x^{- 2})
