Lorelei uses a large oval-shaped tank to feed her horses. Due to recent thunderstorms, the tank is completely full of dirty water that needs to be removed. At time / = 0, Lorelei starts to drain the tank at a rate modeled by g(), measured in gallons per hour, where g is given by the piecewise function: (1-2)(3/+2) 1-2 80= k ap0.491 4
