Web14 de out. de 2010 · It is onto (aka surjective) if every element of Y has some element of X that maps to it: ∀ y ∈ Y, ∃ x ∈ X y = f (x) And for F to be one-to-one (aka bijective ), both of these things must be true. Therefore, by definition a one-to-one function is both into and onto. But you say "an onto function from Y to X must exist." Web3 de jul. de 2016 · Sorted by: 1.

WebAnd if the function is injective we say that this equation can have at most one solution. Now just to remind ourselves what this means. A function is injective, well, draw our arrows here and here. Now if I look at the points in the range, this point has one original and one only. This point has one original and this point has no original.
