Web17 Sep 2024 · The function f: R → R defined by f(x) = x3 is one-to-one. Indeed, if f(x) = f(y) then x3 = y3; taking cube roots gives x = y. In other words, the only solution of f(x) = C is x = 3√C. The function f: R → R defined by f(x) = x3 − x is not one-to-one. Indeed, f(0) = f(1) = f( − 1) = 0, so the inputs 0, 1, − 1 all have the same output 0. Web12 Apr 2024 · What does it mean when a function is onto? In mathematics, a function f from a set X to a set Y is surjective (also known as onto , or a surjection), if for every element y in the codomain Y of f, there is at least one element x in the domain X of f such that f(x) = y.
