From Injective to Surjective: Exploring the Connections between Injection and Bijection in Mathematics - starpoint

In mathematics, a function is a relation between two sets that assigns to each element in one set exactly one element in another set. An injective function, also known as one-to-one, is a function that maps distinct elements in the domain to distinct elements in the range. Conversely, a surjective function, or onto, is a function where every element in the range is paired with an element in the domain. When a function is both injective and surjective, it is considered a bijection, or one-to-one correspondence. This perfect alignment of elements makes bijections particularly useful in various mathematical applications.
