What is Understanding Relations and Functions about?

The document discusses relations and functions. A relation is a set of ordered pairs, while a function is a special type of relation where each x-value is mapped to only one y-value. To determine if a relation is a function, one can use the vertical line test or create a mapping diagram. The domain of a relation is the set of x-values, while the range is the set of y-values. Functions are often written using function notation like f(x) and can be evaluated by substituting values for either x or y.
