4.2 Relations

Front

What is the domain of a relation?

Back

The domain of a relation is the set of all possible input values (x-coordinates) from a set of ordered pairs, table, or graph.

Front

What is the range of a relation?

Back

The range of a relation is the set of all possible output values (y-coordinates) from a set of ordered pairs, table, or graph.

Front

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

Back

{-6, 0, 2, 4}

Front

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

Back

{14, 32, 38, 44}

Front

What are ordered pairs?

Back

Ordered pairs are pairs of numbers (x, y) that represent a point in a coordinate system.

Front

What does the term 'input' refer to in a relation?

Back

The input refers to the x-coordinates or the values that are put into a function or relation.

Front

What does the term 'output' refer to in a relation?

Back

The output refers to the y-coordinates or the values that result from applying the function or relation to the input.

Front

What is a function?

Back

A function is a special type of relation where each input (x) is associated with exactly one output (y).

Front

What is the difference between a relation and a function?

Back

A relation can have multiple outputs for a single input, while a function has only one output for each input.

Front

What is a mapping diagram?

Back

A mapping diagram visually represents the relationship between inputs and outputs in a relation or function.
