Graph the relation. Is the relation a function? Why or why not?
{(–5, 6), (–2, 3), (3, 2), (6, 4)}
No; a domain value has two range values.
Yes; there is only one range value for each domain value.
No; a range value has two domain values.
Yes; there is only one domain value for each range value.
By graphing the points on a coordinate plane:
(-5, 6)
(-2, 3)
(3, 2)
(6, 4)
The points do not pass the vertical line test, meaning there are multiple values of y (or range values) for one value of x (or domain value). Therefore, this relation is not a function.
