A function is a relation that maps to each input value exactly one output value.
Given the function as {(0,1), (2,3), (5,8), (7,2)}, you can rewrite it
- f(0)=1;
- f(2)=3;
- f(5)=8;
- f(7)=2.
Now consider all options:
- the ordered pair (0,2) cannot be add to this function, because then f(0)=2, but you have already that f(0)=1 and output value should be one value;
- the ordered pair (5,3) cannot be add to this function, because then f(5)=3, but f(5)=8 (given) and output value should be one;
- the ordered pair (7,0) cannot be add to this function, because then f(7)=0, but f(7)=2;
- the ordered pair (1,3) can be add to the set, because f(1)=3 is unique ordered pair (with 1st coordinate 1)
