Back

Yes, it is a function because each input has a unique output.

Front

Which of the following sets is a function? (1,2) (2,3) (3,4) (1,5) or (1,2) (2,3) (3,4) (4,5)?

Back

(1,2) (2,3) (3,4) (4,5) is a function.

Front

What are all the x values or inputs in a function called?

Back

Domain.

Front

What are all the y values or outputs in a function called?

Back

Range.

Front

Determine the domain and range: D: {1, 2, 3}, R: {4, 5, 6}. Is it a function?

Back

Yes, it is a function.

Front

What is an example of a non-function?

Back

The set of ordered pairs (1,2), (1,3) is not a function because the input 1 has two different outputs.

Front

If a function has the ordered pairs (2,4), (3,6), (4,8), what is the output when the input is 3?

Back

The output is 6.

Front

What does it mean if a relation is not a function?

Back

It means that at least one input has more than one output.

Identify the domain of the function represented by the set of ordered pairs (1,2), (3,4), (5,6).

Back

The domain is {1, 3, 5}.
