each input is mapped into only one output, then this relation is a function.
The correct option is "Yes, because each input value has only one output value"
A relation maps elements from a set (called the domain, which is the set of the inputs) into elements from another set (called the range, which is the set of the outputs). Such that these mappings generate coordinate pairs (x, y) or (input, output)
A relation is a function only if all the elements in the domain are mapped into only one value in the range.
On the given relation, we have the coordinate pairs:
(6, 3)
(1, 2)
(-1, -1)
(4, 3)
So we can see that each input is mapped into only one output, then this relation is a function.
The correct option is "Yes, because each input value has only one output value"
