need help with this question please and thank u

Consider the paraboloid defined by x=2y?+2z2. (a) Which of the following vector-valued functions gives a parametrization of this paraboloid? O r(u, v) = (1, v, 2u2 + 202) or(u, v) = (212 + 202, 1, 0) or(u, v) = (2v cos(u), 2vsin(u), 4u?) or(u, v) = (2v cos(u), 4v2, 2v sin(u)) (b) Let S be the portion of the paraboloid with 1s ys4 and 0s zs 5, and let f(x,y,z)=5yz2. Set up, but do not evaluate, an iterated double integral in the dudv order equal to / ((x,y,z)d5 du dv
