If you look at a collection of people, you can think of there being a relation between height and age (people generally get taller as they age then remain the same height for a while and then at some point they start getting a bit shorter). This is a relation but not a function because if you input an age people of the same age will have different heights. However, for a particular person, height is a function of age. At any given point in their life (age) that person will be exactly one height. It’s impossible for one person to be 5’ 6” and 6’ 2” at the same time.
