The transformations are a shift of 4 units to the right and a shift of 4 units down.
Which transformation is used?
On the image, we can see that the radius does not change, so we only have translations.
The center goes from (-2, 5) to (2, 1).
So we have a horizontal shift of 4 units (from -2 to 2)
And a vertical shift of -4 units (from 5 to 1).
Then the transformations are a shift of 4 units to the right and a shift of 4 units down.
