coordinate plane, discrete and continuous functions

A way of renaming an equation by replacing y with f(x).

A set of ordered pairs.

Illustrates how each element of the domain is paired with an element in the range.

If any vertical line passes through the graph of a relation no more than once, then it is a function.
