A piece of art is a function of the strokes of the painter's brush.  

In the same way that a mathematical function has one output for every input, a given brushstroke in a piece of art has only one output.

An example of an everyday "real life" function would be that depending on the weather makes a person decide what type of clothing and the amount of clothing they will wear. For example, if it is hot outside you wear less clothing; like a t-shirt and shorts. However, if it is cold, you will wear more clothing like jeans, long sleeve shirt, leggings, and a coat or even more.
