Onto but not one to one function
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.
