WebIf you've got a one-to-one (Injective) function f(x), then you can always define its inverse g(x) = f − 1(x) such that f(g(x)) = g(f(x)). for example, consider f = x3 and g = 3√x. – Omar Nagib Feb 20, 2016 at 19:05 1 @KonstantinosGaitanas both f(g) and g(f) maps from the reals to the reals.

Start … Web30 apr. 2024 · The only solution is f ( x) = x. First, we note that if we have two functions f: X → Y and g: Y → X such that f ∘ g and g ∘ f are identity maps, then f and g must be bijective functions. Now take g = f ∘ f. Further, because f is continuous and bijective, it must be monotonic. Now, you have two cases, f is increasing, or f is decreasing.
