Set up an iterated integral to compute the mass of the region R bounded by y = x^2, y = 4, and x = O with the density function f(x,y) . O \\int_{0}{2) \\int_(0]~{4) f(x,y) dy dx O \\int_{0]~{2) \\int_[0}~{x^2] f(x,y) dy dx O \\int_(0)~{2) \\int_(x^2]~{4) f(x,y) dy dx O \\int_{0]^(4) \\int_(0]^[x^2] f(x,y) dy dx O None of the above
