A technical definition of a function is: a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.
A technical definition of a function is: a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.This means that if the object x is in the set of inputs (called the domain) then a function f will map the object x to exactly one object f(x) in the set of possible outputs (called the codomain).

We can write the statement that f is a function from X to Y using the function notation f:X→Y.
