When you're given the domain and range, i'm just going to lamely draw this.
00:05
What's important is that we have an open circle.
00:10
It looks like it's at negative 2.
00:13
Goes down.
00:14
I don't really care too much about this other stuff.
00:17
But it does, i guess i do care because i have to answer it, that it goes down to negative 1, negative 2 comes back up to 0 -0 -1.
00:34
Comes back down to 1 negative 2 and then back up here except it has a closed dot at 2 7.
00:44
All right, so what's the domain? well, the domain are all the x values and what's important about this is that the further setting goes to the left is negative 2, but you use a parentheses because it's an open circle there.
00:59
And it goes to the right to x equals positive 2 because it's a closed, we, uh, we filled in that dot, so we put a bracket there.
01:10
And as far as the range goes, i don't really like my circle.
01:15
So for the range, those are the y values.
01:18
So i'll point it out is the lowest that the graph goes.
01:22
And i see that it goes down to negative 2...
