How to check bijective function
Web6 feb. 2015 · 1 Answer Sorted by: 2 I'll show you a bijection f: ( 0, 1] → [ 0, 1]. I hope you can transform this into what you want (using any other bijection ( 1 / 2, 1] → ( 0, 1] ). It's actually pretty straightforward. Let f ( 1) = 0, and f ( 1 / n) = 1 / ( n − 1) when n ≥ 1 is an integer. This means that: f ( 1) = 0 f ( 1 / 2) = 1 f ( 1 / 3) = 1 / 2 WebBijective. A function f (from set A to B) is bijective if, for every y in B, there is exactly one x in A such that f(x) = y. Alternatively, f is bijective if it is a one-to-one correspondence between those sets, in other words both injective and surjective. Example: f(x) = x 3 −4x, for x in the interval [−1,2].

WebScore: 4.7/5 (31 votes) . A function is a one-to-one correspondence or is bijective if it is both one-to-one/injective and onto/surjective. Of the functions we have been using as examples, only f(x) = x+1 from ℤ to ℤ is bijective. If there is a bijection from A to B, then A and B are said to have the same size or cardinality; see HowToCount.
