<PRE><B>Question 1145428</B>
.


The post carefully describes what is the value of &amp;nbsp;f(x), &amp;nbsp;but does not describe, &amp;nbsp;what &amp;nbsp;&quot;x&quot; &amp;nbsp;is.



Therefore, &amp;nbsp;the object &amp;nbsp;f(x) &amp;nbsp;&lt;U&gt;IS &amp;nbsp;NOT &amp;nbsp;DEFINED&lt;/U&gt; &amp;nbsp;as a function.



Hence, &amp;nbsp;&lt;U&gt;there is &amp;nbsp;NO &amp;nbsp;SUBJECT &amp;nbsp;to discuss&lt;/U&gt;.



Fake problem.
