1. The monotonic decreasing interval of the function $y=\log _{\frac{1}{5}}|x-2|$ is ( ).
A. $(-\infty, 2)$
B. $(-\infty,-2) \cup(2,+\infty)$
C. $(2,+\infty)$
D. $(0,2) \cup(2,+\infty)$
1. Let $f(x)=|x-2|$, the graph of the function is shown in the right figure. When $x>2$, $\left.y=\log _{\frac{1}{5}} \right\rvert\, x-2|$ is a decreasing function, so the answer is C.
