Question 10263: Graph Point for a Permitted Input

Original question and givens

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

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

raw domain=[0, 1, 2]

sorted distinct declared domain=[0, 1, 2]

queried expression m*x := mul(0, 0)

queried expression m*x = 0

queried expression m*x+b := sum(0, -1)

queried expression m*x+b = -1

x=0;declared domain=[0, 1, 2]

legal graph point=(0, -1)

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

(0, -1)

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