Question

Graph the relation. Is the relation a function? If so why or why not?

(-1,9)
(0,-1)
(-1,4)
(4,9)

Answer 1

Answer: The relationship is not a function

Step-by-step explanation: It doesn't have a continual rate of change or any patterns at all.

Answer 2

It is not a function.

Explanation:

This relation is not a function because a function is a set of points where the x values never repeat.

We can see clearly that the set of points repeats the number -1 in the x value, so it is not a function.
