Question 1164265
.


The basic prescription is THIS:


<pre>

    +-------------------------------------------------------------------------+
    |   If in the row of pairs, you see two pairs with equal first arguments, |
    |            but with different second arguments,                         |
    |                                                                         |
    |              then this row IS NOT a function.                           | 
    +-------------------------------------------------------------------------+
                        |
</pre>


In more compact form, a function with equal inputs &nbsp;(first arguments) &nbsp;must produce equal outputs &nbsp;(second arguments).




So you can easily answer this question &nbsp;ON &nbsp;YOUR &nbsp;OWN, &nbsp;based on this rule.
