Identify Functions/Domain and Range- Lipscomb

Front

What is the definition of a function?

Back

A function is a relation where every input has only ONE output.

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

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 are the x-values in a set of ordered pairs called?

Back

The x-values are called the domain.

Front

What are the y-values in a set of ordered pairs called?

Back

The y-values are called the range.

Front

For the graph with domain {-6,0,2,3,4}, what is the domain?

Back

D: {-6,0,2,3,4}.

Front

For the ordered pairs (2, 11), (9, -3), (7, 21), (-8, 6), what is the domain?

Back

D: {2, 9, 7, -8}.

Front

What is the relationship between domain and range in a function?

Back

The domain consists of inputs, while the range consists of outputs.
