Schritte zur Lösung

Stelle

y

nach

x = y

um:

y = x

Stelle

y

nach

y^{2} - 2 y = x

um:

y = 1 + x + 1, y = 1 - x + 1

f_{1} (x) = x

f_{2} (x) = 1 + x + 1

Um die Schnittpunkte zu finden, löse

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

x = 1 + x + 1 : x = 3

x = 1 - x + 1 : x = 0

1 + x + 1 = 1 - x + 1 : x = - 1

= \int_{- 1}^{0} ∣ f_{2} (x) - f_{3} (x) ∣ d x + \int_{0}^{3} ∣ f_{1} (x) - f_{2} (x) ∣ d x

= \int_{- 1}^{0} 1 + x + 1 - (1 - x + 1) d x + \int_{0}^{3} x - (1 + x + 1) d x

\int_{- 1}^{0} 1 + x + 1 - (1 - x + 1) d x = \frac{4}{3}

\int_{0}^{3} x - (1 + x + 1) d x = \frac{19}{6}

= \frac{4}{3} + \frac{19}{6}
