derivative of 9x+2

\frac{d}{d x} (9 x + 2)

9

Solution steps

\frac{d}{d x} (9 x + 2)

Apply the Sum/Difference Rule:

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

= \frac{d}{d x} (9 x) + \frac{d}{d x} (2)

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

\frac{d}{d x} (2) = 0

= 9 + 0

Simplify

= 9

y (1 - t) d t + t^{2} (1 - t) d y = 0

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

f (x) = 4 x^{2} - 3 x, at x = - 1

x \to 2 lim (x^{2} + 2 x - 7)

\frac{\partial}{\partial y} (sin (2 y))
