Original question and givens

In a fixed Cartesian coordinate system, D={-3, -2, -1} and f:D→R is given by f(x)=(2)x+(0). Which ordered graph point corresponds to the permitted input -3?

  • G001 — In a fixed Cartesian coordinate system, D={-3, -2, -1} and f:D→R is given by f(x)=(2)x+(0). Which ordered graph point corresponds to the permitted input -3?

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

raw domain=[-3, -2, -1]

After

sorted distinct declared domain=[-3, -2, -1]

Conditions: none

The domain is the declared finite integer subset,not automatically all R.The input list must already be distinct.The first coordinate is input,the second output.

Step identifiers and dependencies

Rule: function_graph_declared_domain_scope · Uses: G001

S002 · calculation

Before

queried expression m*x := mul(2, -3)

After

queried expression m*x = -6

Conditions: none

Compute exactly from this step's original operands in the specified order,retaining signs and denominator conditions.

Step identifiers and dependencies

Rule: exact_rational_arithmetic · Uses: G001, S001

S003 · calculation

Before

queried expression m*x+b := sum(-6, 0)

After

queried expression m*x+b = -6

Conditions: none

Compute exactly from this step's original operands in the specified order,retaining signs and denominator conditions.

Step identifiers and dependencies

Rule: exact_rational_arithmetic · Uses: G001, S002

S004 · implies

Before

x=-3;declared domain=[-3, -2, -1]

After

legal graph point=(-3, -6)

Conditions: none

Return a graph point only for a qualified input;do not exchange input and output coordinates.

Step identifiers and dependencies

Rule: graph_point_domain_prerequisite · Uses: G001, S003

Reverse checks

  • 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 — Recompute queried expression m*x+b with exact rational arithmetic, not rounded decimals.
  • S002 · premise_and_result_audit — Recompute queried expression m*x with exact rational arithmetic, not rounded decimals.
  • S001 · premise_and_result_audit — Check against the original data and this step's premises; a one-way implication is not an equivalence.

Result

(-3, -6)

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