And what might seem challenging is throughout this region I have the same lower function, or I guess the lower boundary is y is equal to x squared over 4 minus 1, but I have a different upper boundary. And the way that we can tackle this is by dividing this area into two sections, or dividing this region into two regions, the region on the left and the region on the right, where for this first region, which I'll color even more in yellow, for this first region, over that entire interval in x, and it looks like x is going between 0 and 1, y equals, when x is equal to 1, this function is equal to 1, when x is equal to 1, this function is also equal to 1. So this is the point 1, 1, that's where they intersect. So for this section, this sub-region right over here, y equals square root of x is the upper function the entire time. And then we can set up a different, we can separately tackle figuring out the area of this region, from x is equal to 1 to x is equal to 2, where y equals 2 minus x is the upper function. So let's do it. So let's first think about this first region.
