What is the domain of a function?

Back

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

What is the range of a function?

Back

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

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).

What is a linear function?

Back

A linear function is a function that graphs to a straight line and can be expressed in the form y = mx + b.
