Step-by-step explanation:
1) f(0)=0, f(1)=1, f(2)=2, f(3)=3, then
2) f(0)=0, , then f(1)=1;
, then f(2)=0;
, then f(3)=1
Then , this means that f isn't onto.
3.
- f(0)=0;
, then f(1)=0
, then f(2)=2
, then f(3)=2
Then , this means that f isn't onto.
4. , then f is onto.
5. , this means that f isn't onto.
