.


In &amp;nbsp;Math, &amp;nbsp;there are two traditional forms to write &amp;nbsp;(to determine) &amp;nbsp;a depreciation function.


One way is to use a linear function;  &amp;nbsp;&amp;nbsp;the other way is to use an exponential function.


THEREFORE, &amp;nbsp;if a &amp;nbsp;Math problem talks about depreciation function,

it &amp;nbsp;MUST &amp;nbsp;determine &amp;nbsp;WHICH &amp;nbsp;ONE &amp;nbsp;of &amp;nbsp;TWO &amp;nbsp;POSSIBLE &amp;nbsp;definitions is used.



It is the way to distinct a mathematically correct formulation from illiterate one . . .
