What is the vertical line test?

Back

The vertical line test is a method to determine if a graph represents a function; if a vertical line intersects the graph at more than one point, it is not a function.

Which graph is not a function?

Back

Graph 1.

What does it mean for a function to be linear?

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.
