derivative of

f (x) = cos (2 x)

- sin (2 x) \cdot 2

Solution steps

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

Apply the chain rule:

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

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

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

= - sin (2 x) \cdot 2

(0, 10), (- 9, 1)

f (x) = x^{2} + x - 5

y = x^{2} - x + 7

x = 9

2 x + y = 6
