What is the sequence of transformations that maps triangle def to triangle d’e’f’?

For the first box, you will put "reflect over the y axis". Then in the second box, it would be "translate 2 units to the right".

When we reflect over the y axis, the x coordinate changes from positive to negative. Eg: D = (2,-1) ---> (-2,-1). Then we shift 2 units to the right by adding 2 to the x coordinate, so (-2,-1) ---> (0,-1) which is where point D' is located. Points E and F follow the same pattern.

The answer is D because then triangles DEF and ABC would mapped onto one another
