Witch of the relationsip represent a function

 

Answer:

One-to-One and Many-to-One relations.

Step-by-step explanation:

A function is a relation where the first element (x) is not repeated. The second element (y) can be repeated.

One-to-one relationship where first elements (x) and second elements (y) are not repeated.

Example:

{(1,2), (3,4),(5,6),(7,8)}

First elements: {1, 3, 5, 7}

Second Elements: {2, 4, 6, 8}

Many-to-One relationship where the first elements (x) are not repeated and paired with exactly the same second element (y).

Example:

{(1,3), (2,3), (3,3), (4,3)}

First elements: {1,2,3,4}

Second element: {3}
