Domain and Range

Front

What is the definition of 'Domain'?

Back

The collection of all inputs or x-values in a relation.

Front

What is the definition of 'Range'?

Back

The collection of all outputs or y-values in a relation.

Front

What is the range of the relation given the ordered pairs (2, 11), (9, -3), (7, 21), (-8, 6)?

Back

{11, -3, 21, 6}

Front

What is the range of the relation given the values: -4, -8, -3, 2, 6?

Back

{-8, -4, 4}

Front

What does it mean for a function to have only one output for each input?

Back

It means that for every x-value in the domain, there is exactly one corresponding y-value in the range.

Front

If the domain of a function is {-3, -2, -1, 0, 1, 2, 3}, what is the range if the function outputs the same values?

Back

The range is also {-3, -2, -1, 0, 1, 2, 3}.

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers (x, y) that represent a point in a coordinate system.

Front

How do you find the range from a set of ordered pairs?

Back

Extract the second elements (y-values) from each ordered pair.

Front

What is the difference between domain and range?

Back

Domain refers to the set of all possible input values (x-values), while range refers to the set of all possible output values (y-values).

Front

What is the range of the set of values: {-3, -1, 1, 3, 5, 7, 9}?

Back

{-3, -1, 1, 3, 5, 7, 9}.
