Is the relation shown below a function? Explain

Yes, the relation shown is a function. A relation is considered a function if each input (or x-value) is associated with exactly one output (or y-value). In this case, each x-value (4, 5, 3, 6, 2, 1) is paired with a unique y-value (16, 25, 9, 36, 4, 1) without any repetitions. Therefore, this relation meets the criteria to be classified as a function.
