Final answer:
To find the area enclosed by the curve y = x² - 4x + 3 and the x-axis over the interval [1,3], use the definite integral.
Step-by-step explanation:
To find the area enclosed by the curve y = x² - 4x + 3 and the x-axis over the interval [1,3], we can use the definite integral. First, find the antiderivative of the function: F(x) = 1/3x³ - 2x² + 3x. Then, calculate the definite integral of F(x) from x = 1 to x = 3. The area is equal to the value of the integral.
