All right, we're looking at this graph here, and we're asked to find its domain and range.
00:06
So important things to remember, domain are the x values.
00:13
The range are all the y values.
00:21
So some things to notice here.
00:23
First one is where the graph starts on the left hand side is at this point negative 1, 3.
00:33
And some things that we might notice is that this is a closed point.
00:38
As in it's filled all the way in.
00:40
So this is included.
00:43
This is the opposite of when you look at the other end, the point two zero.
00:50
This is an open point.
00:52
You know that because there's just like an open circle there.
00:55
And that means it's not included in this graph itself...
