Original question and givens Use only the explicitly supplied rule, symbols and finite pair table. Graph appearance supplies no values, and agreement on the listed inputs proves no equivalence on unlisted domains. a=-3, b=-5, inputs=[-3, -2, 0]; f(x)=a*x+b. Give (a,b,sorted distinct inputs,every [x,f(x)] row).
G001 — Use only the explicitly supplied rule, symbols and finite pair table. Graph appearance supplies no values, and agreement on the listed inputs proves no equivalence on unlisted domains. a=-3, b=-5, inputs=[-3, -2, 0]; f(x)=a*x+b. Give (a,b,sorted distinct inputs,every [x,f(x)] row).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
declared symbolic rule or complete finite table After
keep the stated domain and representation distinct Conditions: none
Use only the declared rule or table;agreement on a finite table alone does not establish function equality on an unlisted domain.

S002 · implies Before
[-3, -2, 0] After
[-3, -2, 0] Conditions: none
Deduplicate and numerically order the domain;repeating an input creates no additional function value.
