Final answer:
The image of the point (2,4) after a reflection over the x-axis is (2,-4). This is because reflection over the x-axis inverts the y-coordinate while maintaining the x-coordinate.
Step-by-step explanation:
The question asks for the image of the point (2,4) after a reflection over the x-axis. A reflection over the x-axis inverts the y-coordinate of the point while keeping the x-coordinate the same. Therefore, the point (2, 4) after reflection over the x-axis would become (2, -4).
