D The region D above can be described in two ways. 1. If we visualize the region having "top" and "bottom" boundaries, express each as functions of x and provide the interval of x-values that covers the entire region. "top" boundary 92(x) = "bottom" boundary 91(x) = interval of values that covers the region = 2. If we visualize the region having "right" and "left" boundaries, express each as functions of y and provide the interval of y-values that covers the entire region. "right" boundary f2(y) = "left" boundary fi(y) = interval of y values that covers the region =
