Schritte zur Lösung

Stelle

y

nach

2 y = 3 x

um:

y = \frac{3 x}{2}

Stelle

y

nach

2 y + 4 x = 7

um:

y = \frac{7 - 4 x}{2}

f_{1} (x) = \frac{3 x}{2}

f_{2} (x) = 3

Um die Schnittpunkte zu finden, löse

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

\frac{3 x}{2} = 3 : x = 4

\frac{3 x}{2} = \frac{7 - 4 x}{2} : x = 1

3 = \frac{7 - 4 x}{2} : x = \frac{1}{4}

= \int_{\frac{1}{4}}^{1} ∣ f_{2} (x) - f_{3} (x) ∣ d x + \int_{1}^{4} ∣ f_{1} (x) - f_{2} (x) ∣ d x

= \int_{\frac{1}{4}}^{1} 3 - \frac{7 - 4 x}{2} d x + \int_{1}^{4} \frac{3 x}{2} - 3 d x

\int_{\frac{1}{4}}^{1} 3 - \frac{7 - 4 x}{2} d x = \frac{9}{16}

\int_{1}^{4} \frac{3 x}{2} - 3 d x = 2

= \frac{9}{16} + 2

Vereinfache

= \frac{41}{16}
