Here we see the the graphs of four logarithmic functions.
{{CMD_84}}
{{ENV_85}}
{{CMD_86}}
Match the curves {{MATH_87}}, {{MATH_88}}, {{MATH_89}}, and {{MATH_90}} with the functions
{{MATH_91}}
{{CMD_92}}
First remember what {{MATH_93}} means:
{{MATH_94}}
Moreover, {{MATH_95}} where {{MATH_96}}. So now
examine each of these functions along the horizontal line {{MATH_97}}
{{CMD_98}}
{{ENV_99}}
{{CMD_100}}
Note again (this is from the definition of a logarithm)
{{MATH_101}}
Hence we see:
{{CMD_102}}
{{CMD_103}} {{MATH_104}} corresponds to {{MATH_105}}.
{{CMD_106}} {{MATH_107}} corresponds to {{MATH_108}}.
{{CMD_109}} {{MATH_110}} corresponds to {{MATH_111}}.
{{CMD_112}} {{MATH_113}} corresponds to {{MATH_114}}.
{{CMD_115}}
{{CMD_116}}
{{CMD_117}}
