Question

S={(2,4), (5,-3), (2,3), (0,-6),(1,0)} Is the relation "S" a function?

A) Yes, it is a function.
B) No, it is not a function.

Answer 1

The relation S is not a function because it fails the vertical line test.

Step-by-step explanation:

The relation S is not a function because it fails the vertical line test. To be a function, each x-value can only be associated with one y-value. However, in the relation S, the x-value 2 is associated with both 4 and 3. This violates the rule for functions, so the answer is No, it is not a function (B).
