I've seen this function used for falloff before, but I've never known it's name. It makes it very hard for me to find again, but I've used it many times.
Does anybody know if it has a name/what it is?
y = a + b*(c/(c+x))
It's nice because it's a very tweakable and simple function that doesn't do anything too crazy for unexpected values for x. Also open to knowing other cool falloff functions that might be interesting
