Question

True or False: If a function f:X→Y is invertible, it has a unique inverse.

Answer 1

If a function f:X→Y is invertible, it has a unique inverse. = False .. ❌❌❌

Explanation :-----

If f is invertible, the function g is unique, which means that there is exactly one function g satisfying this property (no more, no less). That function g is then called the inverse of f, and is usually denoted as f −1. If f −1 is to be a function on Y, then each element y ∈ Y must correspond to some x ∈ X.
