To find {{MATH_113}} and {{MATH_114}} that make {{MATH_115}} is continuous at {{MATH_116}}, we need to find {{MATH_117}} and {{MATH_118}} such that {{MATH_119}} Let us return to the continuity checklist at the point {{MATH_120}}. For item {{CMD_121}} notice that {{MATH_122}}, which exists for all values of {{MATH_123}} and {{MATH_124}}.
