relation:
In mathematics, a finitary relation over sets X₁, …, Xₙ is a subset of the Cartesian product X₁ × … × Xₙ; that is, it is a set of n-tuples consisting of elements xᵢ in Xᵢ. Typically, the relation describes a possible connection between the elements of an n-tuple.
function:
Function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable). Functions are ubiquitous in mathematics and are essential for formulating physical relationships in the sciences.
