(Quadric surfaces) Use the quadric surfaces handout on Canvas to answer the following. Do not use a graphing utility for this problem. i. Give the name of each of the surfaces below. ii. Identify the shape of the horizontal traces (parallel to the ry-plane). (Hint: these surfaces may be oriented differently than on the handout - for example, the equation -y = 2x² +522 describes an elliptic paraboloid that opens' along the negative y-axis, and the horizontal traces are parabolas.] (a) 2r2 - y2 + 4 = 1. (b) +-522 +4 = 0. (c) 2 = 22 - 3y2
