area 4/x ,16x, 1/4 x

Solution

area

\frac{4}{x}, 16 x, \frac{1}{4} x

Solution

24 ln (2)

+1

Decimal Notation

16.63553 \dots

Solution steps

To find the intersection points solve

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

\frac{4}{x} = 16 x : x = \frac{1}{2}, x = - \frac{1}{2}

\frac{4}{x} = \frac{1}{4} x : x = 4, x = - 4

16 x = \frac{1}{4} x : x = 0

= \int_{- 4}^{- \frac{1}{2}} ∣ f_{1} (x) - f_{3} (x) ∣ d x + \int_{- \frac{1}{2}}^{0} ∣ f_{3} (x) - f_{2} (x) ∣ d x + \int_{0}^{\frac{1}{2}} ∣ f_{2} (x) - f_{3} (x) ∣ d x + \int_{\frac{1}{2}}^{4} ∣ f_{1} (x) - f_{3} (x) ∣ d x

= \int_{- 4}^{- \frac{1}{2}} \frac{4}{x} - \frac{1}{4} x d x + \int_{- \frac{1}{2}}^{0} \frac{1}{4} x - 16 x d x + \int_{0}^{\frac{1}{2}} 16 x - \frac{1}{4} x d x + \int_{\frac{1}{2}}^{4} \frac{4}{x} - \frac{1}{4} x d x

\int_{- 4}^{- \frac{1}{2}} \frac{4}{x} - \frac{1}{4} x d x = 12 ln (2) - \frac{63}{32}

\int_{- \frac{1}{2}}^{0} \frac{1}{4} x - 16 x d x = \frac{63}{32}

\int_{0}^{\frac{1}{2}} 16 x - \frac{1}{4} x d x = \frac{63}{32}

\int_{\frac{1}{2}}^{4} \frac{4}{x} - \frac{1}{4} x d x = 12 ln (2) - \frac{63}{32}

= 12 ln (2) - \frac{63}{32} + \frac{63}{32} + \frac{63}{32} + 12 ln (2) - \frac{63}{32}

Simplify

= 24 ln (2)
