Answer:


Step-by-step explanation:

Note that the four input values, {3,4,6,11}, are all unique.  Each has exactly one y value associated with it.  This is an important criterion when we're deciding whether a relation is a function or not.

Suppose that we added one more input and its associated output:

{3,4,4,6,11}

If it happened that different values of y were associated with the two 4's, then we know immediatel that this relation is not a function.
