[Cfp-interest 3094] Fwd: Generic Mathematical functions

[Jim Thomas]

Hi JeanHeyd,

In case this isn’t already addressed, please note that in n3219 the typeface for instances of f, f(-x), f(x), x, and -f(x) in the first two sentences in F.10 #3 should be like the typeface for f, f(-z), f(z), z, and -f(z) in G.6.1 #9.
