This problem is a checkpoint for evaluating limits from graphs and tables.  

2. Let $f(x)=\frac { 4 ^ { x } - 3 ^ { x } } { x }$. Copy and complete the table of values below to estimate the value of $\lim\limits_{x \to 0} \frac { 4 ^ { x } - 3 ^ { x } } { x }$.

   $x$	$–0.01$	$–0.001$	$–0.0001$	$0.0001$	$0.001$	$0.01$
   $f(x)$
