bad the scanned document to 6. Submit your assignment on Blackboard. Identify the xy-traces, xz-traces, yz-traces. Then identify the shape of the 3D surface. 1. x2+ y2+ z2 = 25 The graphs of the xy-traces are The graphs of the yz-traces are The graphs of the xz-traces are The surface is a(n) 2. x2 + 4y2 + 322 = 12 The graphs of the xy-traces are The graphs of the yz-traces are The graphs of the xz-traces are The surface is a(n)
