What is the vertical line test?

Back

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

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.
