This idea is the idea behind the Horizontal Line Test. Howto: Use the horizontal line test to determine if a given graph represents a 1-1 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. WebOne-To-One Functions on Infinite Sets. To prove a function is one-to-one, the method of direct proof is generally used. Consider the example: Example: Define f : R R by the rule. f(x) = 5x - 2 for all x R. Prove that f is one-to-one.. Proof: Suppose x 1 and x 2 are real numbers such that f(x 1) = f(x 2). (We need to show x 1 = x 2.). 5x 1 - 2 = 5x 2 - 2. …
