{{MATH_12}}
{{CMD_13}}
Use the linear approximation {{MATH_14}} to estimate the value of {{MATH_15}}.
{{MATH_16}}
{{CMD_17}}
Find the average rate of change of {{MATH_18}} on the interval {{MATH_19}}.
{{MATH_20}}
{{CMD_21}}
Choose the correct statement.
{{CMD_22}}
{{CMD_23}}There exists a point {{MATH_24}} in {{MATH_25}} such that {{MATH_26}}, although the function {{MATH_27}} does not satisfy the conditions on the mean value theorem on {{MATH_28}}.{{CMD_29}}
{{CMD_30}}There exists a point {{MATH_31}} in {{MATH_32}} such that {{MATH_33}}, since the function {{MATH_34}} satisfies the conditions on the mean value theorem on {{MATH_35}}.{{CMD_36}}
{{CMD_37}}There exists a point {{MATH_38}} in {{MATH_39}} such that {{MATH_40}}, but we don't have enough information to find such a point.{{CMD_41}}
{{CMD_42}}There exists no point {{MATH_43}} in {{MATH_44}} such that {{MATH_45}}.{{CMD_46}}
{{CMD_47}}
{{CMD_48}}
{{CMD_49}}
Again, choose the correct statement.
{{CMD_50}}
{{CMD_51}}For each {{MATH_52}} in {{MATH_53}}, there exists a point {{MATH_54}} in {{MATH_55}} such that {{MATH_56}}, although the function {{MATH_57}} does not satisfy the conditions on the mean value theorem on {{MATH_58}}.{{CMD_59}}
{{CMD_60}}For each {{MATH_61}} in {{MATH_62}}, there exists a point {{MATH_63}} in {{MATH_64}} such that {{MATH_65}}, since the function {{MATH_66}} satisfies the conditions on the mean value theorem on {{MATH_67}}.{{CMD_68}}
{{CMD_69}}There may be {{MATH_70}} in {{MATH_71}}, for which there exists a point {{MATH_72}} in {{MATH_73}} such that {{MATH_74}}, but not necessarily every {{MATH_75}} in {{MATH_76}}.{{CMD_77}}

{{CMD_85}}
{{CMD_86}}
Suppose we know that {{MATH_87}} for {{MATH_88}} in {{MATH_89}}. By the mean value theorem, for each {{MATH_90}} in{{MATH_91}}, there exists {{MATH_92}} in {{MATH_93}} such that
{{MATH_94}}
{{CMD_95}}
Recall that we assumed {{MATH_96}} for each {{MATH_97}} in {{MATH_98}}. Use your answer above to bound {{MATH_99}} for {{MATH_100}} in {{MATH_101}} from above and from below.
{{MATH_102}}
{{CMD_103}}
Use the bounds {{MATH_104}} for {{MATH_105}} in {{MATH_106}} you computed in the previous part to approximate {{MATH_107}} from above and below.
{{MATH_108}}
{{CMD_109}}
Let {{MATH_110}} be the linear approximation to {{MATH_111}} at {{MATH_112}} you computed before. We used {{MATH_113}} to approximate {{MATH_114}} and found that {{MATH_115}} is approximately equal to {{MATH_116}}. Using our previous answers, we can deduce that this approximation to {{MATH_117}} is a {{CMD_118}}{{CMD_119}}over approximation{{CMD_120}}{{CMD_121}}under approximation{{CMD_122}}{{CMD_123}}.
