let X be non empty set ; for Y being RealNormSpace
for f being bounded Function of X,the carrier of Y holds modetrans f,X,Y = f
let Y be RealNormSpace; for f being bounded Function of X,the carrier of Y holds modetrans f,X,Y = f
let f be bounded Function of X,the carrier of Y; modetrans f,X,Y = f
f in BoundedFunctions X,Y
by Def5;
hence
modetrans f,X,Y = f
by Def7; verum
