<PRE><B>Question 639777</B>
&lt;br&gt;&lt;font face=&quot;Tahoma&quot;&gt;The rule that would represent this function is:&lt;br&gt;

{{{3^x=y}}} where x is all integer values from 0 to 4.&lt;br&gt;

This is because:&lt;br&gt;

{{{3^0=1}}}&lt;br&gt;

{{{3^1=3}}}&lt;br&gt;

{{{3^2=9}}}&lt;br&gt;

{{{3^3=27}}}&lt;br&gt;

{{{3^4=81}}}&lt;br&gt;

There is no real way to learn these relations.  It just takes practice learning to see numerical patterns.&lt;br&gt;

In this case I was sure the pattern had something to do with 3 because of the nice y values including 3, 9, 27, etc.&lt;br&gt;

I hope this helps!  :)&lt;br&gt;
