Domain and Range Flashcard Review

Front

What is the domain of a set of ordered pairs?

Back

The domain is the set of all first elements (x-values) from the ordered pairs.

Front

What is the range of a set of ordered pairs?

Back

The range is the set of all second elements (y-values) from the ordered pairs.

Front

Given the ordered pairs {(2, 3), (0, 6), (-2, 9), (4, 0)}, what is the domain?

Back

-2, 0, 2, 4

Front

Given the ordered pairs {(2, 3), (0, 6), (-2, 9), (4, 0)}, what is the range?

Back

0, 3, 6, 9

Front

What is a function?

Back

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

Front

Which of the following represents a function: {(1, 2), (1, 3), (2, 4)}?

Back

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

Front

What is the vertical line test?

Back

A method to determine if a relation is a function; if a vertical line intersects the graph more than once, it is not a function.

Given the ordered pairs {(1, 2), (2, 3), (3, 4)}, what is the domain?

Back

1, 2, 3

Front

Given the ordered pairs {(1, 2), (2, 3), (3, 4)}, what is the range?

2, 3, 4

Front

What is the domain of the ordered pairs {(0, 1), (1, 2), (2, 3), (3, 4)}?

Back

0, 1, 2, 3
