Domain and Range of Discrete Functions

Front

What is the domain of a function?

Back

The domain of a function is the set of all possible input values (x-values) for which the function is defined.

Front

What is the range of a function?

Back

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

Given the function {(0,1), (1,-3), (2,-4), (-4,1)}, what is the domain?

Back

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

Front

Given the function {(0,1), (1,-3), (2,-4), (-4,1)}, what is the range?

Back

R: {-4, -3, 1}.

Front

What is a discrete function?

Back

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

Front

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

Back

To find the domain, list all the unique x-values from the ordered pairs.

Front

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

Back

To find the range, list all the unique y-values from the ordered pairs.

Front

What is the domain of the relation {(1,3), (2,4), (3,5)}?

Back

D: {1, 2, 3}.

Front

What is the range of the relation {(1,3), (2,4), (3,5)}?

Back

R: {3, 4, 5}.

Front

If a function has the ordered pairs (4, 2), (5, 3), (6, 4), what is the domain?

Back

D: {4, 5, 6}.
