Hello.
00:02
So here we have three conditions.
00:04
So first we have that y is greater than zero.
00:08
So that's just, well, the line y is equal to zero is just the x -axis.
00:12
So if y is strictly greater than zero, we then have a dashed line and then we have look at everything well above that line.
00:19
So everything above the x -axis is where y is greater than zero.
00:23
We also have the x is less than zero.
00:25
Well, the line x is equal to zero is the y -axis.
00:29
So again, we have a dash line, because of the were strictly less than, and if x is less than zero, well, then went to the left of that line.
00:35
So then we look at everything while, so if y is greater than zero and x is less than zero, then we have everything up in this darker color here...
