What we're going to do using our powers of calculus is find the area of this yellow region. And if at any point you get inspired, I always encourage you to pause the video and try to work through it on your own. So the key here is you might recognize, hey, this is an area between curves. A definite integral might be useful. So I'll just set up the definite integral sign. And so first we need to think about what are our left and right boundaries of our region? Well, it looks like the left boundary is where the two graphs intersect right over here, and the right boundary is where they intersect right over there.
