890.648

Schritte zur Lösung

\int_{4.9}^{7.1} 12 x^{2} - 6 x + 4 d x

Wende die Summenregel an:

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

= \int_{4.9}^{7.1} 12 x^{2} d x - \int_{4.9}^{7.1} 6 x d x + \int_{4.9}^{7.1} 4 d x

\int_{4.9}^{7.1} 12 x^{2} d x = 961.048

\int_{4.9}^{7.1} 6 x d x = 79.2

\int_{4.9}^{7.1} 4 d x = 8.8

= 961.048 - 79.2 + 8.8

= 890.648
