What is a function?

Back

A function is a relation in which each input (or domain value) is associated with exactly one output (or range value).

How can you determine if a graph represents a function?

Back

A graph represents a function if any vertical line drawn through the graph intersects it at most once (Vertical Line Test).

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.

Front

What does it mean for a relation to be a function?

Back

A relation is a function if every element in the domain is paired with exactly one element in the range.

Front

How do you find the range of a function given a specific domain?

Back

To find the range, substitute each value from the domain into the function and collect the resulting output values.
