Consider the following. f(x, y, z) = 3x The x y z-coordinate system is given. There is a solid region with a rectangular base and two labeled faces. The base is in the x y-plane. The first face is in the x z-plane and is bounded by a curve labeled z = 1 ? x^2. The second face is labeled y + z = 2. The top is the surface z = 1 ? x^2. Answer: express the triple integral =1 -1(integral) 1-x^2 0 (integral) 2-z 0 (integral) 3x dydzdx Evaluate the iterated integral:0
