Consider the graph of {{MATH_91}}. {{CMD_92}} {{ENV_93}} {{COMMENT_94}} {{COMMENT_95}} {{COMMENT_96}} {{COMMENT_97}} {{COMMENT_98}} {{CMD_99}} Explain why the limit {{MATH_100}} does not exist. {{CMD_101}} The function {{MATH_102}} is the function that returns the greatest integer less than or equal to {{MATH_103}}. Recall that {{MATH_104}} if {{MATH_105}} can be made arbitrarily close to {{MATH_106}} by making {{MATH_107}} sufficiently close, but not equal to, {{MATH_108}}. So let's examine {{MATH_109}} near, but not equal to, {{MATH_110}}. Now the question is: What is {{MATH_111}}?
