Step-by-step explanation:
we see clearly that the side (leg) lengths changed from 3 units to 1 unit.
so, the scale factor is 1/3.
answer D is correct.
I assume the center of the dilation is the origin (0, 0).
so, C' becomes (-1, 0), A' becomes (-2, 0), B becomes (-2, 1).
it was then reflected across the y-axis (flipped over from the left side of the y-axis to the right side).
C'' becomes (1, 0), A'' (2, 0), B'' (2, 1).
and then it was translated (shifted) by (+1, -2), so that
C''' = D = (2, -2), A''' = F = (3, -2), B''' = E = (3, -1)
