derivative of

f (x) = 2 x^{2} - x - 3

4 x - 1

Solution steps

\frac{d}{d x} (2 x^{2} - x - 3)

Apply the Sum/Difference Rule:

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

= \frac{d}{d x} (2 x^{2}) - \frac{d x}{d x} - \frac{d}{d x} (3)

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

\frac{d x}{d x} = 1

\frac{d}{d x} (3) = 0

= 4 x - 1 - 0

Simplify

= 4 x - 1
