Subject: Math teachers can no longer use f(x)?
Someone I work with pointed out that a recent clothing

line by Lands' End uses f(x) for its registered trademark,

and she was wondering (facetiously) whether math books,

math teachers writing on blackboards (or whatever they

do nowadays), students, and the like will have to pay

royalties to use f(x). Maybe the days of f(x) being the

first notation choice for a function are behind us, and

from this point on it will be g(x)?
