derivative of 2x+y

derivative of

2 x + y

2

Solution steps

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

Treat

y

as a constant

Apply the Sum/Difference Rule:

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

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

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

\frac{d y}{d x} = 0

= 2 + 0

Simplify

= 2

\frac{d}{dd} (d + 7)

y = x + 2 x sin (x)

y = tan (- x + 1)

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

2^{x} - x^{2}
