(1) The function is exponential; it is not<br>
{{{a*(bx)}}}<br>
It is<br>
{{{a*(b^x)}}}<br>
(2) In the given ordered pair, the "-3" indicates the number of bacteria is the number 3 minutes ago.  Not impossible; but unusual....<br>
(3) In the given ordered pair, the "-2" indicates the number of bacteria 3 minutes ago was -2.  That IS impossible....<br>
(4) Two ordered pairs are required to determine an exponential function.  There are an infinite number of exponential functions passing through any one point.<br>
