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.

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. WebSimilarly, we find the range of the inverse function by observing the horizontal extent of the graph of the original function, as this is the vertical extent of the inverse function. If we want to evaluate an inverse function, we find its input within its domain, which is all or part of the vertical axis of the original function’s graph.
