II$.$ Graph each function by hand on graph paper. Be sure to use a large enough graph so that all information can be found clearly. Label all points coinciding with relative extrema and all points of inflection on your graph. All points should be found correct to one decimal place. Include dotted lines to indicate any asymptotes the graph might have. If a function is symmetric or periodic, this behavior should be evident from your graph. At each point where the graph has either a horizontal or vertical tangent line, please sketch a brief tangent line to indicate this. $(8$ points each$)$
