What is the range of a relation?

Back

The range of a relation is the set of all output values (y-values) that correspond to the input values (x-values).

Front

How can you determine if a relation is a function?

Back

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

Front

What is a function?

A function is a special type of relation where each input is associated with exactly one output.

Front

What does it mean if a graph is not a function?

Front

What is the domain of a relation?

Back

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

Front

What is an example of a function?

Back

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

Front

What is an example of a relation that is not a function?

Back

An example of a relation that is not a function is {(1,2), (1,3)}, where the input 1 has two different outputs.
