Algebra 1 Chapter 4 Review B

Front

Is the relation a function? Why?

Back

No, because the x-value 11 has two y-values pair with it.

Front

What test can be used to determine if a graph is a function?

Back

The vertical line test.

Front

What does it mean if a graph passes the vertical line test?

Back

It means that for every x-value, there is only one y-value, so it is a function.

Front

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

Back

Range.

Front

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

Back

Domain.

Front

Does this table represent a function? (Yes/No)

Back

No!

Front

What is a function?

Back

A relation where each input has exactly one output.

Front

If a relation has the pairs (1,2), (1,3), (2,4), is it a function?

Back

No, because the input 1 has two outputs (2 and 3).

Front

What is the definition of a domain in a function?

Back

The set of all possible input values (x-values).

Front

What is the definition of a range in a function?

Back

The set of all possible output values (y-values).
