Select the relations that are functions.
{(a, 1), (6, 1), (c, 1)}
{(a, , , c)}
{(1, , , a)
{(a, , b), (c, c)

Depending on how the input of each function defined,

might be functions.

Step-by-step explanation:

A function between two sets (domain and range) should

The second choice can't be a function since the element from the domain is mapped to more than one element in the range.

Keep in mind that a function should be defined for all elements in its domain. For the first relation to be a function, its domain needs to be . Similarly, the domain for the third and fourth relations should be and
