The following mapping statements describe the transformation of the vertices of the quadrilateral.
A(-3, 2)→ A'(-1,0)
B(-2, 2)→ B'(0, 0)
C(2, 1) → C'(0, -1)
D(-3, 1)→ D'(−1,−1)
which function correctly describes the transformation
1. (x,y) → (x+2, y+2)
2. (x,y) → (x +2, y)
3. (x,y) →(x+2, y-2)
4. (x,y) →(x,y -2)
