What is the definition of a function?
What is the definition of a function?
- A relation where inputs and outputs are interchangeable
- A relation where each input has only one output (correct)
- A relation where inputs and outputs are unrelated
- A relation where each input can have multiple outputs
Which of the following is an example of a function?
Which of the following is an example of a function?
- The set of ordered pairs {(1, 2), (3, 4), (5, 6)}
- The set of ordered pairs {(1, 2), (2, 3), (1, 4)}
- The set of ordered pairs {(1, 2), (1, 3), (1, 4)}

If a relation is not a function, what could be the reason?
If a relation is not a function, what could be the reason?
- The relation has no inputs

Study Notes
Functions and Relations
- A function is a relation between a set of inputs (called the domain) and a set of possible outputs (called the range).
- An example of a function is a relation where every input corresponds to exactly one output.
- If a relation is not a function, it could be because it does not pass the vertical line test, meaning a vertical line can intersect the graph of the relation at more than one point.
- Questions that should NOT be asked based on the provided text are those that require a precise mathematical definition or technical details about functions, as the text does not provide those.
- A common misunderstanding about relations and functions could be that all relations are functions, which is not the case.
- Certain types of questions should NOT be asked based on the provided text because the text does not provide sufficient information to answer more specific or technical questions about functions.
