Answer:
Domain : {10, 15, 19, 32}
Range: {-1, 5, 9}
Step-by-step explanation:
As the table of the relation is given as follows:
<em>X Y</em>
<em>10 5</em>
<em>15 9</em>
<em>19 -1</em>
<em>32 5 </em>
From this table, we can define the relation by combining the ordered pairs from the table. Each and every order pair consists of x-coordinate and corresponding y-coordinate of any corresponding point.
So, the relation from the table can be made as follows:
relation : {(10, 5), (15, 9), (19, -1), (32, 5)}
Domain of a relation consists of all the x-coordinates (first elements) of order pairs.
Range of a relation consists of all the y-coordinates (second elements) of ordered pairs.
So, domain and range of relation will be as follows:
Domain : {10, 15, 19, 32}
Range: {-1, 5, 9}
<em>Note: If there is any </em><em>duplicate</em><em> element in any x or y-coordinate of any ordered pair, it will be written only </em><em>once </em><em>when we determine domain and range. Here, in this example, 5 is duplicate, so, it will be mentioned only one time when we determine the range of this relation.</em>
