Opportunities and Realistic Risks

In simple terms, an invertible function is a mathematical transformation that can be reversed, meaning that it has an inverse function that can restore the original input. This concept is built on the idea of bijectivity, where a function is both injective (one-to-one) and surjective (onto). In other words, every input maps to a unique output, and every output is mapped to exactly one input. To illustrate this, consider a simple function that maps a list of numbers to their squares: f(x) = x^2. This function is not invertible because multiple inputs can map to the same output (e.g., f(1) = f(-1) = 1). However, if we restrict the domain to non-negative numbers, the function becomes invertible.

Yes, any invertible function can be decomposed into a composition of invertible functions, but the converse is not necessarily true.
