ANSWER

r is not a set of ordered pair

EXPLANATION

A relation is a correspondence between two sets.

In a relation, the elements from one set set (domain) maps on to the elements in a second set(co-domain).

The relation can then be written as an ordered pair (x,y).

The given listing is

r={√3,√5,√7, √13}

This is not an ordered pair so it cannot be a relation.

The third choice is correct.

Answer:

Choice C is correct, r is not a set of ordered pairs

Step-by-step explanation:

A relation between sets of data is a collection of ordered pairs which contain one object from each set. If the element x is from the first set and its corresponding object y from the second set, then the objects are said to be related if the ordered pair (x,y) is in the relation.

X comprises of the domain while Y makes up the range.

Therefore, r is not a relation since it is not a set of ordered pairs.
