a triangle has vertices at b(−3, 0), c(2, −1), d(−1, 2). which transformation would produce an image with vertices b″(1, −2), c″(0, 3), d″(3, 0)?

(x, y) → (x + 1, y + 1), (x, y) → (y, x)
(x, y) → (x + 1, y + 1), (x, y) → (−x, y),
(x, y) → (x, −y), (x, y) → (x + 2, y + 2)
(x, y) → (−x, y), (x, y) → (x + 2, y + 2)
