Function Mapping

Function mapping is a way to describe how each input in a set relates to an output in another set. Imagine it as a rule or an instruction that, when given an input (like a number), tells you exactly what output it corresponds to. For example, a function might take a number and double it. This mapping helps us understand the relationship between inputs and outputs clearly and systematically, whether it's simple like doubling numbers or more complex like transforming data in a computer program.
