👉 In the context of mathematics, a refectioner is a mathematical concept that refers to a function or relation that maps each point in its domain onto itself. This concept is often used in geometry and algebra, particularly when dealing with transformations. For example, consider the function f(x) = x^2, which represents a transformation from the real numbers to the real numbers. If we apply this transformation on any point (x, y), then y will also be transformed by f(x). This means
