👉 Reflexiveness is a concept in mathematics and logic that refers to a property of a mathematical expression or function that allows it to be evaluated for all possible inputs. In other words, a function f(x) is said to be reflexive if for every input x, f(x) equals the output of f(f(...f(x)...)). This means that for any input x, f(f(...f(x)...)) equals the output of f(f(...f(x)...), where each time an iteration of
