Domain, Range and Functions Practice

Front

What is the definition of a function?

Back

A function is a relation that assigns exactly one output (y-value) for each input (x-value).

Front

What is the domain of a function?

Back

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

Front

What is the range of a function?

Back

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

Front

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

Back

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

Front

What is an example of a function?

Back

An example of a function is f(x) = 2x + 3, where for each x, there is one corresponding y.

Front

What is the difference between domain and range?

Back

Domain refers to input values (x-values), while range refers to output values (y-values).

Front

How can you determine if a relation is a function?

Back

A relation is a function if no x-value is repeated with different y-values.

Front

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

Back

The domain is {1, 2, 3}.

Front

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

Back

The range is {2, 3, 4}.

Front

If a function has a domain of {0, 1, 2} and a range of {3, 4}, what could be a possible set of ordered pairs?

Back

Possible ordered pairs could be {(0, 3), (1, 4), (2, 3)}.
