SUMMARY
The discussion focuses on calculating the area between the curves defined by the equations \(y=x^2\) and \(x+y=2\), as well as the x-axis. The intersection points of these curves are identified at \(x=-2\) and \(x=1\). To find the area between the curves, the larger area is calculated using the integral \(\int_{-2}^{1} (-x^2 - x + 2)\,dx\), resulting in an area of \(\frac{9}{2}\). The participants clarify the setup for the area calculation, confirming that the correct approach involves integrating the respective functions over the specified intervals.
