derivative of

y = 4 x^{2} - 2 x + (- 9)

8 x - 2

Solution steps

\frac{d}{d x} (4 x^{2} - 2 x - 9)

Apply the Sum/Difference Rule:

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

= \frac{d}{d x} (4 x^{2}) - \frac{d}{d x} (2 x) - \frac{d}{d x} (9)

\frac{d}{d x} (4 x^{2}) = 8 x

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

\frac{d}{d x} (9) = 0

= 8 x - 2 - 0

Simplify

= 8 x - 2
