A.9C · Exponential Functions · unscored study

The table shows some points on the graph of an exponential function. Which function represents the relation shown in the table?

$x$	$f(x)$
−2	64
−1	16
0	4
1	1

$f(x) = \frac{1}{4}(4)^x$
$f(x) = 4\left(\frac{1}{4}\right)^x$
$f(x) = \left(\frac{1}{4}\right)^x$
$f(x) = 4^x$
