Injection (mathématiques) : définition et explications

WebbThe injective function can be expressed as an equation or as a set of items. It is a one-to-one function, f (x) = x + 5. This can be understood by considering the function’s domain items to be the first five natural integers. The injective function f = (1, 6, 2), (2, 7), (3, 8), (4, 9), (5, 10) What is injective function Webb4.3 Injections and Surjections.
