Use y = 3x + 3. What output belongs to input x = 3?
Read the diagram description
A function table with outputs generated by y = 3x + 3.
Show worked steps
Answer: 12
- Multiply the input 3 by 3.
- Add the fixed 3: y = 12.

These quizzes practise concepts within this topic. Multiple-choice answers alone do not demonstrate drawing, conducting an investigation or using a digital tool.
Activities to practise beyond the quiz
- Supported by the guided activity; selecting an MCQ does not demonstrate this action.
- VC2M7A05-C01An input-output rule assigns an output to each permitted input. Record matching values in the same row. On a Cartesian plot, write input first and output second: (x, y).
- VC2M7A05-C02Use the starting output and repeated change to describe a linear pattern. Plot each matching pair with labelled axes. Extend the table using its actual rule, not just a guessed visual continuation.
- VC2M7A05-C03A whole-number stage pattern does not automatically have meaningful half-stages. Distinguish the algebraic extension from the physical construction. Check a spreadsheet against multiple rows, including the fixed term and changes between inputs.
- VC2M7A05-C04Creating, conducting or using the described practical or digital activity; selecting an MCQ answer does not demonstrate this action.
