I'm trying to understand how to determine if a function is injective. I know it involves checking if every element in the domain maps to a unique element in the codomain, but I'm not sure how to apply this in practice.

I am searching for an example of a function that is injective but not necessarily surjective or bijective. I want to understand how such a function behaves and maps inputs to outputs.

Who exactly invented the concept of injective function? Was it a mathematician from a particular era, or perhaps a group of scholars collaborating on a project? Did the invention occur during a time of significant mathematical advancements, or was it a more isolated discovery? Was there a specific problem or question that led to the creation of this function, or was it more of a theoretical development? Could you provide some background information on the individual or group responsible for this significant mathematical concept?

Could you please provide an example of an injective function and explain its characteristics? I'm trying to understand the concept better and having a concrete instance would greatly assist my comprehension. Is there a specific type of mathematical relationship or equation that could serve as an illustrative example? Additionally, how does an injective function differ from other types of functions in terms of its behavior and properties? Thank you for your assistance in clarifying this concept for me.
