An example of a relation in real life that is also a function is the relationship between a person's height and their weight. In this case, the height of a person can be considered as the input, and their weight can be considered as the output. For each person, there is a unique height and weight combination. This means that for a given height, there is only one corresponding weight. Hence, the relationship between height and weight can be defined as a function.
