The correct Answer is:
To find the area enclosed between the curve \( y = 2x - x^2 \) and the x-axis, we can follow these steps: ### Step 1: Identify the curves The first curve is given by: \[ y = 2x - x^2 \] The second curve is the x-axis, which can be represented as: \[ y = 0 \] ### Step 2: Find the points of intersection To find the area between the curve and the x-axis, we need to determine the points where the curve intersects the x-axis. This occurs when \( y = 0 \): \[ 2x - x^2 = 0 \] Factoring the equation: \[ x(2 - x) = 0 \] This gives us the solutions: \[ x = 0 \quad \text{or} \quad x = 2 \] Thus, the points of intersection are \( (0, 0) \) and \( (2, 0) \). ### Step 3: Set up the integral for the area The area \( A \) enclosed between the curve and the x-axis from \( x = 0 \) to \( x = 2 \) can be calculated using the definite integral: \[ A = \int_{0}^{2} (2x - x^2) \, dx \] ### Step 4: Calculate the integral Now we will compute the integral: \[ A = \int_{0}^{2} (2x - x^2) \, dx \] This can be split into two separate integrals: \[ A = \int_{0}^{2} 2x \, dx - \int_{0}^{2} x^2 \, dx \] Calculating each integral: 1. For \( \int 2x \, dx \): \[ \int 2x \, dx = x^2 \] Evaluating from 0 to 2: \[ [x^2]_{0}^{2} = 2^2 - 0^2 = 4 \] 2. For \( \int x^2 \, dx \): \[ \int x^2 \, dx = \frac{x^3}{3} \] Evaluating from 0 to 2: \[ \left[\frac{x^3}{3}\right]_{0}^{2} = \frac{2^3}{3} - \frac{0^3}{3} = \frac{8}{3} \] Now substituting back into the area formula: \[ A = 4 - \frac{8}{3} \] To combine these, we can express 4 as a fraction: \[ 4 = \frac{12}{3} \] Thus: \[ A = \frac{12}{3} - \frac{8}{3} = \frac{4}{3} \] ### Step 5: Final answer The area enclosed between the curve and the x-axis is: \[ \text{Area} = \frac{4}{3} \text{ square units} \]
