Front

What is the domain of a relation?

Back

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

Front

Identify the domain of the relation: {(-6,14), (0,32), (2,38), (4,44)}

Back

{-6, 0, 2, 4}

Front

What is the range of a relation?

Back

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

Front

Identify the range of the relation: {(9, -2), (4, 3), (8, 10), (-4, 8)}

Back

{-2, 3, 8, 10}

Front

For the function {(0,1), (1,-3), (2,-4), (-4,1)}, write the domain and range.

Back

D: {-4, 0, 1, 2} R: {-4, -3, 1}

Front

What are the range values from least to greatest for the relation {(1,3), (5,15), (2,6), (4,12), (3,9)}?

Back

{3, 6, 9, 12, 15}

Front

How do you find the domain of a function?

Back

Identify all the possible x-values that can be input into the function.

Front

Front

What is an ordered pair?

Back

A pair of numbers (x, y) that represents a point in a coordinate system.

Front

What does it mean for a relation to be a function?

Back

Each input (x-value) must have exactly one output (y-value).
