To describe the translation from the pre-image to the image, we analyze the movement of the solid figure (pre-image) to the dashed figure (image). In this case, the solid figure has moved 1 unit to the right and 1 unit up. This means that if we take any point on the solid figure and apply the translation, we will add 1 to the x-coordinate (moving right) and add 1 to the y-coordinate (moving up). Therefore, the translation can be expressed as 'Right 1 unit, Up 1 unit'. This function effectively describes how to move from the original position to the new position.
