(thus 0 is the smallest natural number) The clopen interval is denoted by [a,b) or (a,b] A set is a collection of elements. A u b is the union of a and b and is the set of elements belonging to at least one of the sets. A b intersection of a and b and is the set of elements belonging to both of the sets. A function f from set a to set b (or simply function) is a rule that assigns to each element x of the domain set a to exactly one element called f(x) of the codomain set b. All inputs of x must have a unique output.
