Give an example of a function. give the relation as a set of ordered pairs. use a test such as mapping or the verical line test to show if your set of ordered pairs is a function. an example of a function could be: distance traveled and time, or the cost of a turkey and its weight. you can list your relation as a set of ordered pairs, or as a table. in either case, you must prove the relation is a function using one of the two tools given to you in the prior lessons.
