Step-by-step explanation:
1) f(0)=0, f(1)=1, f(2)=2, f(3)=3, then ![f[\{0, 1, 2, 3\}]=\{0, 1, 2, 3\}](https://tex.z-dn.net/?f=f%5B%5C%7B0%2C%201%2C%202%2C%203%5C%7D%5D%3D%5C%7B0%2C%201%2C%202%2C%203%5C%7D)
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.
, 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.
I think the correct answers are the 1st, 3rd and 5th options.
