D

#### Work Step by Step

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