Identify the sequence of transformations that will reflect a figure over the x−axis and then dilate it by a scale factor of 3.



A (x, y) --------> (x, −y); (x, y)--------> (3x, 3y)

B (x, y)---------> (x, −y); (x, y)--------> (3x, y)

C (x, y---------->)(−x, y); (x, y)-------->(3x, 3y)

D (x, y)---------->(−x, y); (x, y)-------->(x, 3y)
