derivative f(x)=sqrt(x)+2

Lösung

ableitung von

f (x) = x + 2

\frac{1}{2 x}

Schritte zur Lösung

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

Wende die Summen-/Differenzregel an:

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

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

\frac{d}{d x} (x) = \frac{1}{2 x}

\frac{d}{d x} (2) = 0

= \frac{1}{2 x} + 0
