Question & Answer
Is this relation a function?
1 Answer
Verified archiveYes, this relation is a function.
A function is defined as a relation where each input (x-value) has exactly one output (y-value). In this table, each x-value (0, 6, 1, 3) corresponds to only one y-value. Even though the x-value 3 appears twice, it still maps to one specific y-value each time (8 and -9), so it can still be considered as a function.
