Webb17 apr. 2024 · When f is an injection, we also say that f is a one-to-one function, or that f is an injective function. Notice that the condition that specifies that a function f is an injection is given in the form of a conditional statement. As we shall see, in proofs, it is usually easier to use the contrapositive of this conditional statement. WebbIn Mathematics, a bijective function is also known as bijection or one-to-one correspondence function. The term one-to-one correspondence should not be confused with the one-to-one function (i.e.) injective function. In this article, we are going to discuss the definition of the bijective function with examples, and let us learn how to prove …

In mathematics, an injective function (also known as injection, or one-to-one function) is a function f that maps distinct elements of its domain to distinct elements; that is, f(x1) = f(x2) implies x1 = x2.
