A. The mapping rule for this transformation is "multiply the coordinates of the original quadrilateral by 2."
B. To find the new coordinates of quadrilateral , we need to apply the mapping rule to each vertex of the original quadrilateral. For example, if the coordinates of the upper left vertex of the original quadrilateral are (x1, y1), then the coordinates of the corresponding vertex of the new quadrilateral will be (2x1, 2y1). We need to do this for all four vertices to find the new coordinates of quadrilateral .
C. To plot the coordinates of the quadrilateral on the coordinate grid, we need to know the specific coordinates of each vertex. Since we don't have that information, we cannot plot the quadrilateral.
