D Question 3 2 pts Suppose you are trying to compute the double integral ( f(z, y)dA and you notice that this region looks much nicer under a change of coordinates x = 2utv, y = u+5 to a region S (e.g., a "rectangle") in the wv-plane. When reformulating as an integral with respect to u, v we get an integral f ( 2u + v, u + 5)adudu for some number or. What is this number o? O -1 O 2 O -2 O 1
