A propositional function in logic, is a statement expressed in a way that would assume the value of true or false, except that within the statement is a variable (x) that is not defined or specified, which leaves the statement undetermined. Of course, x could also consist of several variables.
As a mathematical function, A(x) or A(x1, x2, · · ·, xn), the propositional function is abstracted from predicates or propositional forms. As an example, let’s imagine the predicate, “x is hot”. The substitution of any entity for x will produce a specific proposition that can be described as either true or false, even though “x is hot” on its own has no value as either a true or false statement. However, when you assign x a value, such as lava, the function then has the value true; while if you assign x a value like ice, the function then has the value false.
Propositional functions are useful in set theory for the formation of sets. For example, in 1903 Bertrand Russell wrote in The Principles…
