For example, if you want to show a bijection between A = {0, 1, 2, 3, 4} and B = {8, 9, 10, 11, 12} you could write

[tex]f: A \to B, f(a) = a + 8[/tex]

(for finite sets, you can also write it out as: define f by f(0) = 8, f(1) = 9, ..., f(4) = 12).

How about it? If you mean: how about a bijection, you are asking half a question. A bijection is always betweenhow about with (0,1)?

Compuchip is correct. Think over it.
