1. ### Suppose R is the shaded region in the figure, and f(x,y) is a continuous function on R. Find the limits of integration for the?

Note that the line at the bottom (connecting points (-4, -3) to (1, 1)) has equation y = 4x/5 + 1/5. Then, the region can be described by y = 4x/5 + 1/5 to y = 3 with x in [-4, 1]. In other words, the integral equals ∫(x = -4 to 1) ∫(y = 4x/5 + 1/5 to 3...
