Directions:. The following is an exploration of surfaces and understanding how to graph functions and parameterizations in 3D. For this assignment we will be using the online plotter CalePlot3D which you can access at https://c3d. libretexts. org/CalcPlot3D/index. html. For each of the questions below, respond to the questions fully. For any graphs that are produced, click on the three lines located at the top left and choose print plot. You are welcomed to type your submission, however, keeping your graphs and pages organized will be fine as well. 1. Getting Familar with the Software (a) Clicking on the menu next to "Add Graph", choose "Implicit Surface". A preprogrammed equation should load. What type of quadric surface is this? (b) Consider the quadric surface r' - y' + 2- =4. Plot this graph and change the window size so that -4
