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

Back

How do you find the domain of a set of ordered pairs?

Back

To find the domain, list all the first elements (x-values) of the ordered pairs.

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

Back

To find the range, list all the second elements (y-values) of the ordered pairs.

What is a mapping diagram?

Back

A mapping diagram visually represents a function by showing how each input is paired with an output.

What is an example of a function?

Back

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