What is the domain of this relation? (9, 8) (-15, 20) (5, -4) (5, 8) write the numbers in the domain with commas between them (for example, {1, 2, 3}). domain: { }

Domain: {-15, 5, 9}

Step-by-step explanation:

A relation is a set of ordered pairs in the form of (x, y) that can be plotted in a coordinate plane.  The Domain of a relation is the set of all the x-values represented in the set of given ordered pairs.  In the set of four ordered pairs given there are four x-values in each pair:  9, -15, 5 and 5.  When we identify the domain, we put the values in order from least to greatest and if a number repeats, in this case 5, we only need to include it once.  This gives us the final set of {-15, 5, 9}.
