This worksheet is practice for the students on how to find the domain and range of a relation, decide if something is a function or not, and to express a relation using a table, graph, and mapping diagram. endobj Write each of the following as a relation, state the domain and range, then determine if it is a function. A relation is a set of one or more ordered pairs. The vertical line represents a value in the domain, and the number of intersections with the graph represent the number of values to which it corresponds.

We say "the output is a function of the input." The input values make up the domain, and the output values make up the range. Included are 5 different task sheets. /ca 1.0 In addition, since we can find a vertical line that intersects the graph more than once, we conclude that the graph is not a function. To determine whether a given relation is a function or not, one needs first to find out the input values, then the output values. Determine the domain and range of the following relation and state whether it is a function or not: \(\{(4, 3), (2, 6), (0, 3), (3, 5), (3, 7)\}\). d224f870063a40e098457059835651f2, 055c0d457aa04cdf98c57925f2da174b Algebra 2 relations and functions worksheet answers can be a useful tool for these scholars.
