So this question gives us a relation.
00:04
It has three coordinate pairs or points in there.
00:07
It has the point negative 1 -0.
00:12
It has the point negative -1 -6 and negative -18.
00:16
So it's wanting us to find out is this relation is a function or not.
00:22
And we need to remember that for our relations would be a function, every input or x value must only have one output or y value.
00:31
You.
00:32
So an easy way to think this through is to list your domain and range and map or draw lines from your domain to your range.
00:41
So your domain, you have negative one and negative one and negative one, but i don't have to write negative one three times to show that, hey, we've got a negative one and the domain.
00:53
And then for your range, you have a zero, a six, and an eight.
01:01
And then if you map it, that negative one goes to the zero.
01:05
It also goes to the six, then it also goes to the eight.
01:08
So what this is saying is that when you plug a negative one into this relation, you're going to get three different outputs...
