WebDec 5, 2024 · 1. If you want to check that a function is injective, of course you need the formal definition. A function f: A → B is injective if and only if f ( x) = f ( y) implies x = y for all x, y ∈ A. Let's take your second example, f: ( 0, ∞) → R, where f ( x) = ln x / x. Supopse f ( x) = f ( y), that is, ln x x = ln y y. WebHow to Determine Whether Two Functions Are Inverses. Step 1: Input the first function you are testing into your original function.

WebAnother answer Ben is that yes you can have an inverse without f being surjective, however you can only have a left inverse. A left inverse means given two functions f: X->Y and g:Y->X. g is an inverse of f but f is not an inverse of g. So take any element x in X and g(f(x)=x.
