To find: the domain and range of each relation
![Check Mark](/static/check-mark.png)
Answer to Problem 37E
Domain =
Range =
Yes, because it passes the vertical line test.
Explanation of Solution
Given information: The coordinates are
x | 2 | 9 | 8 | -9 |
y | -3 | 0 | -3 | 8 |
Calculation:
Since all the possible values of x is a domain. So, the domain value is
All the possible values of y represent the range. So, the range is
Plot a graph by using table of values to get,
It passes the vertical line test because for each value of x there is only one value of y. Hence this relation is a function.
