The correct Answer is:
To solve the problem, we need to find the area \( A \) bounded by the curves \( y \leq e - |x - e| \) and \( y \geq 0 \), and then compute \( \log_e(A) \). ### Step-by-Step Solution: 1. **Understand the function**: The function \( y = e - |x - e| \) can be rewritten as: \[ y = \begin{cases} e - (x - e) & \text{if } x \geq e \\ e + (x - e) & \text{if } x < e \end{cases} \] This simplifies to: \[ y = \begin{cases} 2e - x & \text{if } x \geq e \\ x & \text{if } x < e \end{cases} \] 2. **Find the points of intersection**: We need to find where \( y = e - |x - e| \) intersects with \( y = 0 \). - For \( x < e \): Set \( x = 0 \) to find the intersection: \[ 0 = e - (e - x) \implies x = 0 \] - For \( x \geq e \): Set \( y = 0 \): \[ 0 = e - (x - e) \implies x = 2e \] Thus, the points of intersection are \( (0, 0) \) and \( (2e, 0) \). 3. **Determine the vertex of the triangle**: The vertex of the triangle formed by the lines occurs at \( (e, e) \), where the two lines meet. 4. **Calculate the area of the triangle**: The triangle has a base along the x-axis from \( (0, 0) \) to \( (2e, 0) \) with a height reaching up to \( (e, e) \). - The base length is \( 2e \) (from \( 0 \) to \( 2e \)). - The height is \( e \) (from the x-axis to the point \( (e, e) \)). - The area \( A \) of the triangle is given by: \[ A = \frac{1}{2} \times \text{base} \times \text{height} = \frac{1}{2} \times 2e \times e = e^2 \] 5. **Calculate \( \log_e(A) \)**: Now we need to find \( \log_e(A) \): \[ \log_e(A) = \log_e(e^2) = 2 \] ### Final Answer: Thus, \( \log_e(A) = 2 \).
