Schritte zur Lösung

Um die Schnittpunkte zu finden, löse

f_{i} (x) = f_{j} (x)

6 x - 2 = x^{2} + 2 x + 2 : x = 2

6 x - 2 = 1 : x = \frac{1}{2}

x^{2} + 2 x + 2 = 1 : x = - 1

= \int_{- 1}^{\frac{1}{2}} ∣ f_{2} (x) - f_{3} (x) ∣ d x + \int_{\frac{1}{2}}^{2} ∣ f_{1} (x) - f_{2} (x) ∣ d x

= \int_{- 1}^{\frac{1}{2}} x^{2} + 2 x + 2 - 1 d x + \int_{\frac{1}{2}}^{2} 6 x - 2 - (x^{2} + 2 x + 2) d x

\int_{- 1}^{\frac{1}{2}} x^{2} + 2 x + 2 - 1 d x = \frac{9}{8}

\int_{\frac{1}{2}}^{2} 6 x - 2 - (x^{2} + 2 x + 2) d x = \frac{9}{8}

= \frac{9}{8} + \frac{9}{8}
