Input-output relationship
A function maps each allowed input to one output. Formula, table, and graph are different representations of the same relationship.
Parameters and graph
Parameters change slope, position, amplitude, or rate of change. Read the key features before plotting individual points.
Domain and interpretation
The domain states which inputs are allowed. In a real model, also check whether the output is physically meaningful.
Πεδίο ορισμού
Use a suitable representation, state the rule, and keep every numerical or algebraic step equivalent. Finish with estimation, an inverse operation, or substitution as a check.
Σύνολο τιμών
Use a suitable representation, state the rule, and keep every numerical or algebraic step equivalent. Finish with estimation, an inverse operation, or substitution as a check.
Μονοτονία
Use a suitable representation, state the rule, and keep every numerical or algebraic step equivalent. Finish with estimation, an inverse operation, or substitution as a check.
Ακρότατα
Use a suitable representation, state the rule, and keep every numerical or algebraic step equivalent. Finish with estimation, an inverse operation, or substitution as a check.

Worked arithmetic example
5 equal groups contain 9 objects each. How many objects are there, and how can the answer be checked?
- 1Write repeated addition: 9 + 9 + 9 + 9 + 9.
- 2Connect it to 5 × 9.
- 3Check with division: 45 ÷ 5 = 9.

Thinking and explanation example
Explain “Πεδίο ορισμού” in your own words and use a picture, objects, a table, or a simple measurement to support it.
- 1State what is known and what is being found.
- 2Choose one clear representation.
- 3Explain what it shows and check that the answer is sensible.
A complete explanation connects the correct idea, a clear representation, and a sensible check.
