Okay, so here we have the region r, which is a triangle with vertex is negative 2, negative 1, the first one.
00:11
The second one, oh, negative 2, 1.
00:16
Okay, so negative 2, 1.
00:19
The second one is negative 2, negative 3, and the third one is 4, negative 3.
00:35
So let's sketch this triangle first.
00:39
Okay, so negative 1, negative 2 here, 1 here.
00:45
Then, okay, negative 1, negative 2.
00:50
Then here we are going to have along the y -axis, negative 3, and here 4.
00:59
So 1, 2, 3 and 4.
01:03
Okay, this is the x -axis, this is the y -axis.
01:06
Okay, so the first vertex is here, which is negative, oh, it's negative to 1, so it's here.
01:17
Okay, the second one is negative 2, negative 3, which is here, and the last one is 4 negative 3, which is here.
01:31
Okay, so our triangle, okay, our 3.
01:38
Triangle is this one here.
01:45
Let me draw it better.
01:49
Okay perfect...
