Discrete Domain and Range

Front

What is the definition of 'domain' in a relation?

Back

The domain of a relation is the set of all possible 'x' values (input values) that can be used in the relation.

Front

What is the definition of 'range' in a relation?

Back

The range of a relation is the set of all possible 'y' values (output values) that result from the relation.

Front

What does it mean for a relation to be 'discrete'?

Back

A discrete relation consists of distinct, separate values, often represented as individual points.

Front

What does it mean for a relation to be 'continuous'?

Back

A continuous relation includes all values within a given range, often represented as a line or curve.

Front

Identify the domain of the relation: {(1, 2), (3, 4), (5, 6)}

Back

The domain is {1, 3, 5}.

Front

Identify the range of the relation: {(1, 2), (3, 4), (5, 6)}

Back

The range is {2, 4, 6}.

Front

What is a function?

Back

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

Front

Is the relation {(1, 2), (1, 3)} a function?

Back

No, because the input '1' is associated with two different outputs (2 and 3).

Front

What is the range of the following table? {(-1, 0), (0, 1), (1, 2)}

Back

The range is {0, 1, 2}.

Front

Identify the domain of the following relation: {(2, 3), (4, 5), (6, 7)}

Back

The domain is {2, 4, 6}.
