F(x) more than just a math symbol?

Today, I learned about functions, and finding the slope. We used the equation: f(x) = mx+b, and I was listening to kpop this evening, and I noticed something very interesting:

One of my favorite kpop group's name is F(x)

This will math not be so terrible in the days that follow. (more function on the way!) So now when I'm doing my math, I can listen to them, and I won't feel so sad about math. (which I usually love, but slopes get me every time!)

What I find interesting about this, is that they named their group after a math equation. I wonder if they think us Americans do to be funny. Anyway, have a happy Tuesday! Planning on watching some Batman cartoons before bed. (shhh! Don't tell the Avengers!)
