Domain and Range (Discrete)

Front

What is the Domain?

Back

The domain of a function is the set of all possible input values (x-values) that the function can accept.

Front

Identify the domain of the relation {(0,1), (1,-3), (2,-4), (-4,1)}.

Back

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

Front

What is the Range?

Back

The range of a function is the set of all possible output values (y-values) that the function can produce.

Front

Identify the range of the relation {(0,1), (1,-3), (2,-4), (-4,1)}.

Back

R: {-4, -3, 1}

Front

What is true about the relation?

Back

Its domain is {-2, 0, 1, 3}.

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

Back

D: {-6, 0, 2, 4}

Front

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

Back

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

What is a discrete function?

Back

A discrete function is a function that only takes on specific, separate values, often represented as distinct points.

Front

How do you find the domain of a function given a set of ordered pairs?

Back

The domain is found by listing all the first elements (x-values) of the ordered pairs.

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

Back

The range is found by listing all the second elements (y-values) of the ordered pairs.
