The values of two functions, f and g, are given in a table. One, both, or neither of them may be exponential. 
Give the exponential models for those that are. 



<pre>
x      -2      -1 	0 	1 	 2

f(x) 	0.5 	1.5 	4.5 	13.5    40.5     <<<---===  f(x) = {{{0.5*3^(x+2)}}}

g(x)    12 	6 	3 	1.5 	 0.75    <<<---===  g(x) = {{{12*2^(-x-2)}}}
