Hi, i'm david and i'm here to have you answering your question.
00:03
Now let me bring up your question here.
00:06
In the question here we want to use the shell method to find the volume of the revolution solid.
00:12
Here we want to scan the graph first.
00:22
Here we have the x and this will be the y.
00:25
The function on the form was fx, which is the x bar minus 4.
00:32
So if we try to scan the graph here, it will be something like this form.
00:39
And then we will have between the minus 2 and minus 1.
00:44
This will be, i will say this one will be the minus 2.
00:49
I will make it might be wider.
00:52
I will put this one will be the minus 2.
00:54
This will be the minus 1.
00:56
And this will be the region we want to rotate it about the line x to the 4.
01:03
So 1, 2, 3, 4...
