1. Problem Description
The problem asks us to find the domain and range of a relation given in a table and determine if the relation is a function. The table provides and values where represents the input and represents the output.
2. Solution Steps
The domain is the set of all -values. From the table, the -values are -4, -19, -3, 5, and
2
0. So, the domain is $\{-19, -4, -3, 5, 20\}$.
The range is the set of all -values. From the table, the -values are 19, 10, -14, 17, and -
1
6. So, the range is $\{-16, -14, 10, 17, 19\}$.
A relation is a function if each -value has only one corresponding -value. Looking at the table, we can see that each -value (-4, -19, -3, 5, and 20) is associated with exactly one -value (19, 10, -14, 17, and -16, respectively). Thus, the relation is a function.
3. Final Answer
Domain:
Range:
Is the relation a function?: Yes
