Answer:
We need the following three rigid motions:
i) Reflection around y-axis, ii) Translation three units in the -y direction, iii) Translation four units in the -x direction.
Step-by-step explanation:
We need to perform three operations on pentagon ABCDE to create pentagon A'B'C'D'E':
i) Reflection around y-axis:
 (Eq. 1)
 (Eq. 1)
ii) Translation three units in the -y direction:
 (Eq. 2)
 (Eq. 2)
iii) Translation four units in the -x direction:
 (Eq. 3)
 (Eq. 3)
We proceed to proof the effectiveness of operations defined above by testing point D:
1)  Given.
 Given.
2)  By (Eq. 1)
 By (Eq. 1)
3)  By (Eq. 2)
 By (Eq. 2)
4)  By (Eq. 3)/Result
 By (Eq. 3)/Result
