OnetoOne Functions and their Inverses Page 1 of 7 2.8: OnetoOne Functions and Their Inverses OnetoOne Functions Example 1 Deciding whether a Function is OnetoOne Is the function ? = 3 onetoone? Example 2 Deciding whether a Function is OnetoOne Is the function ? = 2 onetoone? Example 3 Deciding whether a Function is OnetoOne Is the function ? = 2 with domain [0, ) onetoone? ? 1 ? 2 whenever 1 _2. Definition of a OnetoOne Function A function ? with domain is called a onetoone function if no two elements of have the same image, that is, Horizontal Line Test A function is onetoone if and only if no horizontal line intersects its graph more than once.
