Front

What determines if a relation is a function?

Back

A relation is a function if each input (x value) has exactly one output (y value).

Front

Front

If a relation has repeating x values, what can be said about it?

Back

It is not a function.

Front

What is the set of all inputs in a relation called?

Back

Domain

Front

Can a relation have multiple outputs for the same input?

Back

No, if it does, it is not a function.

Front

What is an example of a function?

Back

f(x) = 2x + 3 is a function because each x value has one corresponding y value.

Front

What is an example of a relation that is not a function?

Back

The relation {(1, 2), (1, 3)} is not a function because the input 1 has two different outputs.

Front

What is the difference between discrete and continuous data?

Back

Discrete data can only take specific values, while continuous data can take any value within a range.
