Graph the relation. Is the relation a function? Why or why not? {(–1, 9), (0, –1), (–1, 4), (4, 9)} Yes; there is only one range value for each domain value. No; a domain value has two range values. No; a range value has two domain values. Yes; there is only one domain value for each range value.

No, the relation is not a function.

Step-by-step explanation:

Since x = -1 produces y = 9 and y = 4, the relation (–1, 9), (0, –1), (–1, 4), (4, 9) is not a function.

Step-by-step explanation:

Given points:

Same domain of -1 has two different range values of 9 and 4

The graph therefore doesn't pass the vertical line test, so it is not a function.

Correct option is:

because they could drop even lower..
