Answer:- D) translation, then reflection
Explanation :-
We can see in the given picture figure 1 in second quadrant is transformed to figure 2 by now change in its shape or rotation.There is no change in the y coordinate of the points of the figure 1 to figure 2 , but x coordinate translated by factor of +6 , Therefore The translation of fig. 1 to fig. 2 is given by (x,y)→(x+6,y) .
After that figure 2 is transformed to figure 3 where its x coordinates isn't change but there is change in the sign of y coordinate(i.e. it becomes negative).Thus this transformation is reflection (x,y)→(x,-y) across the x axis.
