So this question wants me to state the domain.
00:03
So we're going to do domain first.
00:09
So i'm just going to remind myself my domain is for this left x value.
00:13
So these are x's to the furthest right.
00:17
X value.
00:18
Now, because i have arrows on both sides, it lets me know it's going to keep going to the left.
00:25
So negative infinity.
00:26
And it's going to keep going to the right to infinity.
00:29
I'm now going to do my range.
00:32
Now my range works with my y values.
00:35
It's the lowest to the highest.
00:41
Y value.
00:43
So again, because i have an arrow here, it lets me know it's going down forever.
00:49
So it would be negative affinity.
00:52
And the highest it goes is 6.
00:53
It would never ever go past 6.
00:55
Now, because there is a line at 6, it does include the value 6.
01:00
So i put a bracket.
01:03
Now, i want to find where it's increasing, decrease.
01:06
Or constant.
01:08
So let's move this down...
