The correct Answer is:
To find the area bounded by the curves \( y = 2 - |2 - x| \) and \( y = \frac{3}{|x|} \), we will follow these steps: ### Step 1: Redefine the equations based on the absolute values The equation \( y = 2 - |2 - x| \) can be split into two cases: - For \( x < 2 \): \( |2 - x| = 2 - x \) so \( y = 2 - (2 - x) = x \) - For \( x \geq 2 \): \( |2 - x| = x - 2 \) so \( y = 2 - (x - 2) = 4 - x \) The equation \( y = \frac{3}{|x|} \) can also be split: - For \( x > 0 \): \( |x| = x \) so \( y = \frac{3}{x} \) - For \( x < 0 \): \( |x| = -x \) so \( y = -\frac{3}{x} \) ### Step 2: Identify the intersection points To find the area, we need to determine the intersection points of the curves. We will consider the cases for \( x \geq 0 \) and \( x < 0 \). 1. **For \( x \geq 0 \)**: - Set \( x = \frac{3}{x} \) (since \( y = x \) and \( y = \frac{3}{x} \)) - This leads to \( x^2 = 3 \) or \( x = \sqrt{3} \) (we discard the negative root since we are considering \( x \geq 0 \)). 2. **For \( x \geq 2 \)**: - Set \( 4 - x = \frac{3}{x} \) - Rearranging gives \( 4x - x^2 = 3 \) or \( x^2 - 4x + 3 = 0 \) - Factoring gives \( (x - 1)(x - 3) = 0 \), so \( x = 1 \) and \( x = 3 \). ### Step 3: Determine the area between the curves The area can be calculated by integrating the upper curve minus the lower curve between the intersection points. 1. **From \( \sqrt{3} \) to \( 2 \)**: - Upper curve: \( y = x \) - Lower curve: \( y = \frac{3}{x} \) - Area \( A_1 = \int_{\sqrt{3}}^{2} \left( x - \frac{3}{x} \right) dx \) 2. **From \( 2 \) to \( 3 \)**: - Upper curve: \( y = 4 - x \) - Lower curve: \( y = \frac{3}{x} \) - Area \( A_2 = \int_{2}^{3} \left( (4 - x) - \frac{3}{x} \right) dx \) ### Step 4: Calculate the integrals 1. **Calculate \( A_1 \)**: \[ A_1 = \int_{\sqrt{3}}^{2} \left( x - \frac{3}{x} \right) dx = \left[ \frac{x^2}{2} - 3 \ln |x| \right]_{\sqrt{3}}^{2} \] Evaluating this gives: \[ A_1 = \left( \frac{2^2}{2} - 3 \ln 2 \right) - \left( \frac{(\sqrt{3})^2}{2} - 3 \ln \sqrt{3} \right) = \left( 2 - 3 \ln 2 \right) - \left( \frac{3}{2} - \frac{3}{2} \ln 3 \right) \] 2. **Calculate \( A_2 \)**: \[ A_2 = \int_{2}^{3} \left( (4 - x) - \frac{3}{x} \right) dx = \left[ 4x - \frac{x^2}{2} - 3 \ln |x| \right]_{2}^{3} \] Evaluating this gives: \[ A_2 = \left( 12 - \frac{9}{2} - 3 \ln 3 \right) - \left( 8 - 2 - 3 \ln 2 \right) = \left( \frac{15}{2} - 3 \ln 3 \right) - \left( 6 - 3 \ln 2 \right) \] ### Step 5: Combine the areas The total area \( A \) is: \[ A = A_1 + A_2 \] ### Final Area Calculation After performing the calculations and simplifications, we find: \[ A = 4 - \frac{3}{2} \ln 3 \] Thus, the area bounded by the curves is: \[ \boxed{4 - \frac{3}{2} \ln 3} \]

To find the area bounded by the curves \( y = 2 - |2 - x| \) and \( y = \frac{3}{|x|} \), we will follow these steps: ### Step 1: Redefine the equations based on the absolute values The equation \( y = 2 - |2 - x| \) can be split into two cases: - For \( x < 2 \): \( |2 - x| = 2 - x \) so \( y = 2 - (2 - x) = x \) - For \( x \geq 2 \): \( |2 - x| = x - 2 \) so \( y = 2 - (x - 2) = 4 - x \) The equation \( y = \frac{3}{|x|} \) can also be split: ...
