Basically the title. Let's say you want to describe an aspect of the dating, how would you do that mathematically, where x is the said aspect and y as importance of it in the success and x,y≥0

For example, I want to describe how crucial sense of humour in dating. I would choose the y = ln(x) (For those who don't know how it looks, here is wiki page with a graph: https://en.m.wikipedia.org/wiki/Natural_logarithm ), where x is "quality" of that aspect, and y as it's importance. I would choose this formula because you can still still succeed without it (hence why the importance only starts with at 1 and not from zero) and also it can only take you so far, so the graph stops growing as rapidly as it started, meaning that you can even be a stand up comedian, but it still won't matter if you have only sense of humour.

So, My question is this: How would describe a)Height, b) Intelligence, c) Experience in that way?

Edit: You can take place a value in the hypothetical unit. Like, for a height, you can take 0 as a 5'5 and move it from there with 0'1 as a step
