Answer
D
Work Step by Step
We are given that $f(x)=4^{-x}$. In order to find out which graph matches this function, we can find the value of $f(1)$.
$f(1)=4^{-1}=\frac{1}{4^{1}}=\frac{1}{4}$
Therefore, $f(x)$ matches Graph D, as it is the only graph that contains the ordered pair $(1,\frac{1}{4})$.
