let F be Field; for E being FieldExtension of F
for T being non empty finite Subset of E
for x being b2 -evaluating Function of (card T),E holds rng (hom_Ext_eval (x,F)) c= the carrier of (RAdj (F,T))
let E be FieldExtension of F; for T being non empty finite Subset of E
for x being b1 -evaluating Function of (card T),E holds rng (hom_Ext_eval (x,F)) c= the carrier of (RAdj (F,T))
let T be non empty finite Subset of E; for x being T -evaluating Function of (card T),E holds rng (hom_Ext_eval (x,F)) c= the carrier of (RAdj (F,T))
let x be T -evaluating Function of (card T),E; rng (hom_Ext_eval (x,F)) c= the carrier of (RAdj (F,T))
now for o being object st o in rng (hom_Ext_eval (x,F)) holds
o in the carrier of (RAdj (F,T))let o be
object ;
( o in rng (hom_Ext_eval (x,F)) implies o in the carrier of (RAdj (F,T)) )assume A:
o in rng (hom_Ext_eval (x,F))
;
o in the carrier of (RAdj (F,T))
rng (hom_Ext_eval (x,F)) = { (Ext_eval (p,x)) where p is Polynomial of (card T),F : verum }
by lemphi1;
then consider p being
Polynomial of
(card T),
F such that B:
o = Ext_eval (

thus
o in the

verum end;
hence
