The complete total map f:Fin(3)→Fin(8) has images=[6, 2, 1] indexed from 0; Fin(3)={0,…,2}. Every table entry must lie in the target type. List every [i,f(i)] in source-index order, using [] for an empty source.
G001 — The complete total map f:Fin(3)→Fin(8) has images=[6, 2, 1] indexed from 0; Fin(3)={0,…,2}. Every table entry must lie in the target type. List every [i,f(i)] in source-index order, using [] for an empty source.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.
Before
f:Fin(3)→Fin(8);source indices start at0
After
complete total map,not a partial program function
Conditions: none
Every legal source element has one codomain value.Fin(0) is empty;an outside query is ill-typed,not a hole of a partial function at a legal input.
Rule: total_finite_mapping_scope · Uses: G001
Before
f input=0∈Fin(3)
After
f(0)=6∈Fin(8)
Conditions: none
Audit source and codomain eligibility for every entry;an unqueried entry may not be illegal.
Rule: complete_mapping_entry · Uses: G001, S001
Before
f input=1∈Fin(3)
After
f(1)=2∈Fin(8)
Conditions: none
Audit source and codomain eligibility for every entry;an unqueried entry may not be illegal.
Rule: complete_mapping_entry · Uses: G001, S002
Before
f input=2∈Fin(3)
After
f(2)=1∈Fin(8)
Conditions: none
Audit source and codomain eligibility for every entry;an unqueried entry may not be illegal.
Rule: complete_mapping_entry · Uses: G001, S003
Before
[6, 2, 1]
After
[[0, 6], [1, 2], [2, 1]]
Conditions: none
List[i,f(i)] for every source index;do not invent graph points for unused codomain elements.An empty source has an empty graph.
Rule: complete_finite_function_graph · Uses: G001, S004
S005 · premise_and_result_audit — Check against the original data and this step's premises; a one-way implication is not an equivalence.S004 · premise_and_result_audit — Check against the original data and this step's premises; a one-way implication is not an equivalence.S003 · premise_and_result_audit — Check against the original data and this step's premises; a one-way implication is not an equivalence.S002 · premise_and_result_audit — Check against the original data and this step's premises; a one-way implication is not an equivalence.S001 · premise_and_result_audit — Check against the original data and this step's premises; a one-way implication is not an equivalence.[[0, 6], [1, 2], [2, 1]]
The full substitutions and premise checks give the original answer; source identity,format and status are unchanged.
