WebWe know that ln(x) is onto, as it is the inverse of ex: R → (0,∞). But it’s domain is not R. We make the domain R by “attaching” the half-line from (−∞,0] at y = 0. Then, its not one-to-one, as f(−1) = f(−2) = 0. (c) f is neither one-to-one nor onto. Solution. There are many examples, for instance, f(x) = x2. Not onto, since ...

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.

Cross-multiply both sides of the equation to simplify the equation. x 2 = x 1. x 1 = x 2. We’ve just shown that x 1 = x 2 when f (x 1) = f (x 2 ), hence, the reciprocal function is a one to one function. Example 1.

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. raw file app
