A one-to-one function is a type of function where each input value corresponds to a unique output value, meaning no two different inputs produce the same output. This characteristic ensures that the function does not map multiple elements from its domain to a single element in its range, making it easier to determine the invertibility of the function. Understanding one-to-one functions is essential as it highlights how different elements relate to each other within functions, revealing their special properties.
