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=0, b=-9, inputs=[0, 1, 3]; 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=0, b=-9, inputs=[0, 1, 3]; 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.

Step identifiers and dependencies

Rule: representation_scope · Uses: G001

S002 · implies

Before

[0, 1, 3]

After

[0, 1, 3]

Conditions: none

Deduplicate and numerically order the domain;repeating an input creates no additional function value.

Step identifiers and dependencies

Rule: distinct_numeric_domain · Uses: G001, S001

S003 · calculation

Before

x=0 ax := mul(0, 0)

After

x=0 ax = 0

Conditions: none

Evaluate a·x first;do not replace the rule by a(x+b).

Step identifiers and dependencies

Rule: exact_rational_arithmetic · Uses: G001, S002

S004 · calculation

Before

x=0 ax+b := sum(0, -9)

After

x=0 ax+b = -9

Conditions: none

Then add the intercept b,fully substituting this input.

Step identifiers and dependencies

Rule: exact_rational_arithmetic · Uses: G001, S003

S005 · implies

Before

x=0; ax+b=-9

After

[0, -9]

Conditions: none

Each input is paired with its calculated output;the ordered pair lists input before output.

Rule: representation_table_row · Uses: G001, S004

S006 · calculation

Before

x=1 ax := mul(0, 1)

After

x=1 ax = 0

Conditions: none

Reverse checks

  • S011 · premise_and_result_audit — Check against the original data and this step's premises; a one-way implication is not an equivalence.
  • S010 · premise_and_result_audit — Recompute x=3 ax+b with exact rational arithmetic, not rounded decimals.
  • S009 · premise_and_result_audit — Recompute x=3 ax with exact rational arithmetic, not rounded decimals.
  • S008 · premise_and_result_audit — Check against the original data and this step's premises; a one-way implication is not an equivalence.
  • S007 · premise_and_result_audit — Recompute x=1 ax+b with exact rational arithmetic, not rounded decimals.
  • S006 · premise_and_result_audit — Recompute x=1 ax with exact rational arithmetic, not rounded decimals.
  • 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 — Recompute x=0 ax+b with exact rational arithmetic, not rounded decimals.
  • S003 · premise_and_result_audit — Recompute x=0 ax with exact rational arithmetic, not rounded decimals.
  • 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.

Result

(0, -9, [0, 1, 3], [[0, -9], [1, -9], [3, -9]])

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