Observe the table:
\a.
\Assume that the ages are the domain.
\Write the domain and range.
\Since the ages are the domain, the average points per game are the range.
\Domain:
\The domain of the relation is the set of all first (![\"\"](\"http://www.mathskey.com/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=8da2268e35b6b6daab9c47f71c4c8bf4.png\")

b.
\Write a relation of ordered pairs for the data.
\Observe the table the ordered pairs for the relation, the members of the domain are the -values and the members of therange are the -values.
The ordered pairs for the relation is ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=597d3e5fcb7ec73d9b49fc1702502b75.png\")

c.
\State whether the relation is discrete or continuous.
\The domain is a set of individual points.
\Thus, the relation is discrete.
\d. Graph the relation.
\![\"\"](\"/userfiles/23-64-4a.gif\")
The relation is a function as each element of the domain is paired with exactly one element of the range.
