I just finished watching Steven Wittens talk about fun with Maths, and I really, really like his teaching style and examples. In particular, his breakdown of simply using some value x as an input, and returning a unique value with a transformation function across a range of values, really stuck with me as a simple way to understand and achieve very complex behavior.
I decided to recreate some examples of my own random f(x), where each function returns something different. A range of values is given, as well as the results as each key is modified by the function.
