Solution
To find the volume of the solid formed by rotating the region bounded by the curves y = -x^2 + 6x - 8 and y = 0 about the x-axis, we can use the disk method.
The disk method formula is V = π ∫ [R(x)]^2 dx from a to b, where R(x) is the radius of the disk at x and [a, b] is the interval over which we integrate.
Here, the radius R(x) of the disk at x is the distance from the x-axis to the curve y = -x^2 + 6x - 8, which is simply the value of y at x. So, R(x) = -x^2 + 6x - 8.
We need to find the points where the curve
