Below is a graph of the region bounded by y = x2, y = -2x, and y = 4. If you wanted to calculate the area of this region by making horizontal slices, which of the following integrals would you write down? (Extra question: Why would horizontal slices be easier than vertical slices here?) 2 0 124 -2x - x2 dx 0 12 212 - (-2y) dy Joy2 - 2ydy
