Plug the domain into the function and the y values you get will be [0, 7) and [5,11)
Putting the ranges for each piece together, the lowest number in the range is 0 and the highest number is 11. The zero is included since the inequality sign was ansl equal to. The 11 is not included since it was not equal to.
[0,11) is the range.
