Section 15.9 Written HW Part 1 (10 points) Evaluate ffR 48 xy (M where R is the square bounded by the vertices (1, 0), (0, 1), (1, 2), (2, 1). Use the transformation 1:. = x + y, 17 = x + 3/. When you are done, think about this: if the transformations were not given to you, would you have been able to come up with them on your own?
