A point A(2, 3, 4) is reflected over the x-axis and then rotated 180 degrees about the x-axis. Determine the final coordinates.
💡 Hint: Apply transformations sequentially.
Given a point at (1, 2, 3), derive its transformation if it's reflected over the x-axis and then scaled by 2.
💡 Hint: Consider how each transformation modifies the coordinates.
