To find: the domain and range of relation
Answer to Problem 33E
Domain =
Range =
No, because it does not pass the vertical line test.
Explanation of Solution
Given information: The coordinates are
x | 1 | 1 | 1 | 1 |
y | -2 | 4 | -6 | 0 |
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,
Since it does not pass the vertical line test because for single value of xthere are several values of y. Hence this relation is not a function.
