Consider the iterated integral 4 9+y / / erx-y dxd y 1 4+y Part A. By using the change of variables u = 1/36 y and U = y, sketch the given region of integration and its image under the transformation T(x, y) = (u, v) Label all curves and axes. Part B. Compute the Jacobian. You must clearly and coherently justify your work - show your steps in your calculation. You cannot provide only the final answer. Circle your final answer for each part
