Which rule describes the composition of transformations that maps pre-image ABCD to final image A"B"C"D"?

almond37 [142]

The correct option will be: $r_{x-axis} \circ T_{-6,1} (x,y)$

Explanation

We can see in the diagram that distances of $A' , B', C'$ and $D'$ from the x-axis are equal with the distances of $A, B, C$ and $D$ from the x-axis respectively.

That means, $ABCD$ is first reflected about the x-axis to form $A'B'C'D'$

Now, $A'', B'', C''$ and $D''$ are located at 6 units left and 1 unit up from $A', B', C'$ and $D'$ .

Thus, for getting the final image $A''B''C''D''$ , we are first reflecting $ABCD$ about the x-axis and then translated it 6 units left and 1 unit upward.
