This problem gives us a graph and wants us to answer a lot of graph characteristics about it.
00:05
And the first being x intercepts and y intercepts.
00:07
So we have x intercepts at, and that's where it's crossing the x -axis.
00:11
We have x -tercepts at 0 and 2 .50.
00:17
And that looks to be the only two places it's crossing the x -axis.
00:20
The y -intercept is also 0 .0.
00:22
That's the only point, the origin, that can be considered both an x -intercept and a y -intercept because it's where they both intersect.
00:28
So only one y intercept.
00:29
For the domain, we want to show all the x values that are possible, and it looks like this domain is covering x values from negative 3, this first point here, all the way up to positive 3 at the very end here.
00:45
And we'll use brackets for both of those to show that those numbers are included.
00:48
For the range, the lowest value we look to hit is negative 1, again included, so bracket, and then the highest value that we hit seeing, or that we see we hit on.
00:59
On this graph is 2, so bracket as well.
01:02
Increasing, decreasing, a constant.
01:04
Those are the x values that show the behavior as we move from left to right...
