The correct Answer is:
To determine whether the statement "The area of the region bounded by the curves \( y = x^2 + 2 \), \( y = x \), \( x = 0 \), and \( x = 1 \) is \( \frac{7}{16} \)" is true or false, we will calculate the area step by step. ### Step 1: Identify the curves and the area to be calculated We have the curves: - \( y = x^2 + 2 \) (a parabola opening upwards) - \( y = x \) (a straight line) - Vertical lines \( x = 0 \) and \( x = 1 \) We need to find the area between these curves from \( x = 0 \) to \( x = 1 \). ### Step 2: Find the points of intersection To find the area between the curves, we first need to determine where the curves intersect. Set \( x^2 + 2 = x \): \[ x^2 - x + 2 = 0 \] Calculating the discriminant: \[ D = (-1)^2 - 4 \cdot 1 \cdot 2 = 1 - 8 = -7 \] Since the discriminant is negative, the curves do not intersect. ### Step 3: Determine which curve is on top For \( x \) in the interval \( [0, 1] \): - At \( x = 0 \): \( y = 0^2 + 2 = 2 \) and \( y = 0 \) (the line) - At \( x = 1 \): \( y = 1^2 + 2 = 3 \) and \( y = 1 \) Thus, \( y = x^2 + 2 \) is above \( y = x \) in the interval \( [0, 1] \). ### Step 4: Set up the integral for the area The area \( A \) between the curves from \( x = 0 \) to \( x = 1 \) is given by: \[ A = \int_{0}^{1} ((x^2 + 2) - x) \, dx \] ### Step 5: Calculate the integral Now, simplify the integrand: \[ A = \int_{0}^{1} (x^2 + 2 - x) \, dx = \int_{0}^{1} (x^2 - x + 2) \, dx \] Now, compute the integral: \[ A = \int_{0}^{1} (x^2 - x + 2) \, dx = \left[ \frac{x^3}{3} - \frac{x^2}{2} + 2x \right]_{0}^{1} \] Calculating the upper limit: \[ A = \left( \frac{1^3}{3} - \frac{1^2}{2} + 2 \cdot 1 \right) - \left( \frac{0^3}{3} - \frac{0^2}{2} + 2 \cdot 0 \right) \] \[ = \left( \frac{1}{3} - \frac{1}{2} + 2 \right) \] Finding a common denominator (6): \[ = \left( \frac{2}{6} - \frac{3}{6} + \frac{12}{6} \right) = \frac{2 - 3 + 12}{6} = \frac{11}{6} \] ### Step 6: Conclusion The area \( A = \frac{11}{6} \) square units, which is not equal to \( \frac{7}{16} \). Thus, the statement is **False**.
