We're asked to find the area of the region closed by the following two curves.
00:05
We have our f of x is equal to x squared.
00:09
And we have our g of x, which is equal to 2 minus x squared.
00:18
First, we're trying to find where do these curves intersect.
00:25
So we'll equal them to each other.
00:29
X squared is equal to 2 minus x squared.
00:36
Let's move our x to the same side.
00:40
So we have 2x squared is equal to 2, divided by 2, and we get x squared is equal to 1, meaning that our x must be equal to plus or minus 1.
00:55
These are going to be our boundaries.
00:58
So when we integrate, we'll have the integral from negative 1 to 1...
