I guess you just mean to graph the two functions with their respective restricted domains.
Make a table for each function and then graph them. (if not using a graphing calculator)
Code:
x | f(x)=x^2 -1
------------------
2 | 3 (not included in graph since x < 2)
1 | 0
0 | -1
-1| 0
-2| 3
Code:
x | f(x)=2 - x
------------------
2 | 0 (included in graph since x >= 2)
3 | -1
4 | -2
5 | -3
See my crude graph.
