Schritte zur Lösung

\int_{- 3}^{0} \frac{y}{3} + y + 4 d y

Wende die Summenregel an:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int_{- 3}^{0} \frac{y}{3} d y + \int_{- 3}^{0} y + 4 d y

\int_{- 3}^{0} \frac{y}{3} d y = - \frac{3}{2}

\int_{- 3}^{0} y + 4 d y = \frac{14}{3}

= - \frac{3}{2} + \frac{14}{3}

Vereinfache

- \frac{3}{2} + \frac{14}{3} : \frac{19}{6}

= \frac{19}{6}
