👉 Invertibility refers to a mathematical property of a function or an operation, which means that if we substitute any value for the input variable in the formula, the result should be the same as if we had not substituted it. In other words, if we substitute a value into the function repeatedly and keep track of the values until we get back to the original input, then the function will never return to the original state or value. This property is crucial for understanding how functions behave in many mathematical contexts
