Another way to look at this proposition is as a proposition with two variables. The assertion that p(x, y) is a tautology could be quantified as (∀x)R((∀y)R(p(x, y))) or (∀y)R((∀x)R(p(x, y)))

WebSo for example, if x denotes a real number, then • ∃x : x2 = 4 is true, since 2 is an x for which x2 = 4. On the other hand, ∀x : x2 = 4 is clearly false; not all numbers, when squared, are equal to 4. • ∀x : x2+1 > 0 is true, but ∀x : x2 > 2 is false, since for example x = 1 doesn’t satisfy the predicate.
