Answer:
(1, -1)
Step-by-step explanation:
The three transformations are ...
(x, y) ⇒ (-x, y) . . . . . reflection over the y-axis
(x, y) ⇒ (x, -y) . . . . . reflection over the x-axis
(x, y) ⇒ (-x, -y) . . . . . rotation 180°
Then the composition of the three transformations is ...
(x, y) ⇒ (x, y) . . . . . . back to the original position
A(1, -1) ⇒ A'(1, -1)
