Web7 de jul. de 2024 · A function f is said to be one-to-one if f(x1) = f(x2) ⇒ x1 = x2. No two images of a one-to-one function are the same. To show that a function f is not one-to-one, all we need is to find two different x -values that produce the same image; that is, find x1 ≠ x2 such that f(x1) = f(x2). Exercise 6.3.1. WebYou want a function from f:N -> N which is onto but not one-to-one. Onto means that every number in N is the image of something in N.
