tommy equation

[tommy1729]

The problem might be

p( f(x) ) = f(ax) + b f(cx)

is nice but does it mean

p^[z] ( f(x) ) = f(a^z x) + b^z f(c^z x)

or does

p^[z] ( f(x) ) = f(a^z x) + b f(c^z x)

or something else ?

I noted that since p(0) = 0 :

Let f(A) = 0

p(f(A)) = f(aA) + b f(cA) = 0

Not sure what to make of that ...
