Let
{{MATH_1}}
Determine if the following limits exist. If they exist, compute them {{CMD_2}}analytically{{CMD_3}} using the {{CMD_4}}limit laws{{CMD_5}} and {{CMD_6}}techniques for computing limits{{CMD_7}}. If a limit {{CMD_8}}does not exist{{CMD_9}}, write `DNE' and explain why. Do not use a table of values, a graph, or L'H{{CMD_10}}opital's rule to justify your answer.

Let's give an explanation as to why this is true. When {{MATH_20}} is
greater than {{MATH_21}},
{{MATH_22}}
{{CMD_23}}As {{MATH_24}} approaches {{MATH_25}} from the right, {{MATH_26}} is {{CMD_27}}{{CMD_28}}positive{{CMD_29}}{{CMD_30}}negative{{CMD_31}}{{CMD_32}}zero{{CMD_33}}{{CMD_34}} and approaching zero while at the same time, {{MATH_35}} approaches {{MATH_36}}. {{CMD_37}} Therefore, as {{MATH_38}} approaches {{MATH_39}} from the right, {{MATH_40}} is positive and grows {{CMD_41}}{{CMD_42}}arbitrarily large{{CMD_43}}{{CMD_44}}arbitrarily small{{CMD_45}}{{CMD_46}}. {{CMD_47}} Hence,
