Match each function formula with the corresponding transformation of the parent function y = (x - 1)2

1. y = - (x - 1)2 translated right by 1 unit
2. y = (x - 1)2 + 1 translated down by 3 units
3. y = (x + 1)2 reflected over the y-axis
4. y = (x - 2)2 reflected over the x-axis
5. y = (x - 1)2 - 3 translated up by 1 unit
6. y = (x + 3)2 translated left by 4 units
