a reflection across the x-axis, followed by a counter-clockwise rotation 90° about the origin, followed by a translation 4 units down and 4 units to the left
C
a counter-clockwise rotation of 90° about the origin followed by a translation 4 units to the right
D
no sequence of translations, rotations, and reflections because the images are not congruent
