derivative of

f (x) = 2 x^{2} + x - 1, at a = - 1

4 x + 1

Solution steps

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

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} (1)

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

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

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

= 4 x + 1 - 0

Simplify

= 4 x + 1

y^{^{'}} = 5 y^{2} + x y^{2}, y (0) = 1

\frac{d}{d x} (\frac{- 8 x - 2}{9 x - 4})

\int (cos (2 x))^{4} d x

\frac{d y}{d x}, y^{3} = x^{5}

e^{a x}
