By reflecting a function to fit within a particular domain, the result is what I'm calling laced-up functions (as if you were able to wrap the function around a particular width). Above is f(x) = sin(x) and below is a cubic, f(x) = x^3.
Above left is f(x) = x*sin(x) and above right is another cubic. Below is f(x) = x^2 and sqrt(x).
Above x+sin(x). Below 1/x and tan(x).
