Question 4383: Complete Finite Predicate Partition

Original question and givens

The explicitly finite integer domain is U=[-7, -1, 0, 1, 7] and P(x) means x=1. Give (elements satisfying P, elements not satisfying P), each sorted increasingly.

• G001 — The explicitly finite integer domain is U=[-7, -1, 0, 1, 7] and P(x) means x=1. Give (elements satisfying P, elements not satisfying P), each sorted increasingly.

Definition and scope

Use the original question domain, assumptions and cited MKO definitions. This item has second-context mathematical and bilingual review, with the model, answer and every arithmetic step independently recomputed from the original parameters; the source question remains a candidate.

Step-by-step derivation

complete finite U=[-7, -1, 0, 1, 7]

universal on empty domain=True;existential on empty domain=False

x=-7;predicate=eq 1

P(x)=No

x=-1;predicate=eq 1

P(x)=No

x=0;predicate=eq 1

P(x)=No

x=1;predicate=eq 1

P(x)=Yes

x=7;predicate=eq 1

P(x)=No

[[-7, No], [-1, No], [0, No], [1, Yes], [7, No]]

T=[1];F=[-7, -1, 0, 7];T∪F=U and T∩F=∅

Result

([1], [-7, -1, 0, 7])

The full substitutions and premise checks give the original answer; source identity,format and status are unchanged.
