Please notice, &amp;nbsp;that &amp;nbsp;THERE &amp;nbsp;IS &amp;nbsp;NO &amp;nbsp;any equation in your post.


The formula, &amp;nbsp;where you see the equality sign &amp;nbsp;&quot; = &quot;, &amp;nbsp;is &amp;nbsp;NOT &amp;nbsp;AN &amp;nbsp;EQUATION.


It is &amp;nbsp;THE &amp;nbsp;DEFINITION &amp;nbsp;of a function.



&lt;H3&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;Fake problem.&lt;/H3&gt;
