Given: r = (√3, √5, √7, √13) why is r not a relation?

r is a sequence

r is not a set of ordered pairs

r is a set of rational numbers

r is a series

Option B.

Step-by-step explanation:

Given:

r is a set of rational numbers.

We need to find the reason why r is not a relation.

A relation is a set of ordered pairs, where x-coordinate is domain and y-coordinate is range. It is defined as

Since r is not a set of ordered pairs, therefore r is not a relation.

Thus, the correct option is B.
