Which transformation maps hexagon 1 into 3?

1: reflection along the y-axis and rotation of 180° by the origin o
2: reflection along the y-axis and reflection along the x-axis
3: reflection along the x-axis and rotation of 90° by the origin o
4: rotation of 270° by the origin o

Let's look at the possibilities:

1. Reflection along the y-axis and rotation of 180 degrees by the origin 0. (Gives us 4 and then 2 in the end)

2. Reflection along the y-axis and reflection along the x-axis. (Gives us 4 and then 3 in the end)

3. Reflection along the x-axis and rotation 90 degrees by the origin 0. (Gives us 4 and then 1 in the end)

4. Rotation of 270 degrees by the origin 0. (Gives us 2 in the end)

Option 2 is the answer.

Best of luck!
