Functions, Domain, and Range

Front

What is the Domain?

Back

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

Front

What is the Range?

Back

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

Front

Does this represent Y as a function of X?

Back

Yes, if each input (x) has exactly one output (y).

Front

Write the domain for {(-4; 3), (2; 1), (0;3), (-3;-2)}

Back

{-4; -3; 0; 2}

Front

Which relation is NOT a function?

Back

{(1,-5), (-1,6), (1,5), (6,-3)} because the input 1 has two different outputs.

Front

What is a function?

Back

A relation where each input has exactly one output.

Front

How do you find the domain of a function?

Back

Identify all the possible x-values that can be input into the function.

Front

How do you find the range of a function?

Back

Identify all the possible y-values that can be output from the function.

Front

What is an example of a function?

Back

f(x) = 2x + 3 is a function because for every x, there is one y.

Front

What is a non-function?

Back

A relation where at least one input has multiple outputs.
