A relation is a function if each input (domain value) has exactly one corresponding output (range value). In the given table, each age (input) is unique and paired with only one height (output); there are no repeated ages with different heights.

Answer:

Yes, this relation is a function. Each age (input value) is associated with exactly one height (output value), with no input having multiple distinct outputs.
