Original question and givens

Given the explicit declaration A={11, 12, 13, 14}, B={-46, 0, 47}, ordered pairs=[(11, 47), (12, -46), (13, 0), (14, 47)] and a total function f:A→B, list the attained range in increasing order.

  • G001 — Given the explicit declaration A={11, 12, 13, 14}, B={-46, 0, 47}, ordered pairs=[(11, 47), (12, -46), (13, 0), (14, 47)] and a total function f:A→B, list the attained range in increasing order.

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

S001 · implies

Before

source roles = [qf-function-range-set, range, no-required-domain, []]

After

derived = [[ACTUAL_attained_range_set_STRING]]

Conditions: none

BASE sources do not acquire a generic legacy operation/domain or unknown-metadata ban.Retain metadata WITHOUT using it as an answer oracle.PULSE/legacy enforce their exact source keys,operation/domain.Do not impose universal tuples,/1 or input bounds.

derived = [[11, 12, 13, 14]]

Conditions: none

RAW A/B/C are distinct SAFE integers.Legacy injective limits100,but PULSE has NO such cap.Sort ONLY a derived work table,retaining original lists.

Conditions: none

PULSE rejects EXACT duplicate RAW rows BEFORE totality,not as a legal No.Legacy injective FIRST checks raw length≤200,then normalizes identical rows as one pair.Do not exchange these policies;type-check EVERY raw cell first.

After

derived = [[Yes, Yes, Yes, Yes], [1, 1, 1, 1], Yes]

Conditions: none

A total function needs BOTH every declared input AND every row qualified.PULSE validity may legally return No;other queries and legacy injective REQUIRE actual totality BEFORE lookup.Empty A/table can be valid;unattained B labels remain.
