WebA function is said to be invertible when it has an inverse. It is represented by f −1. Condition for a function to have a well-defined inverse is that it be one-to-one and Onto or simply bijective. Example : f(x)=2x+11 is invertible since it is one-one and Onto or Bijective. WebIf f: A → B is a function, then there are multiple possible ways to define an inverse. You can require that g R: B → A satisfies f ( g R ( x)) = x for all x ∈ B. Such a g R is called a right-inverse, and exists if f ist surjective (also called onto). You can require that g L: B → A satisfies g L ( f ( x)) = x for all x ∈ A. mellow streamWebSep 17, 2024 · Now we can show that to check B = A − 1, it's enough to show A B = I n or B A = I n.
