3. For any function $y=f(x)$, in the same Cartesian coordinate system, the graphs of the functions $y=f(x-1)$ and $y=f(-x+1)$ are always
(A) symmetric with respect to the $x$-axis
(B) symmetric with respect to the line $x=1$
(C) symmetric with respect to the line $x=-1$
(D) symmetric with respect to the $y$-axis
(B)
3. 【Analysis and Solution】The graphs of $f(x)$ and $f(-x)$ are symmetric with respect to the line $x=0$, and the graphs of $f(x-1)$ and $f(-x+1)$ are symmetric with respect to the line $x=1$.
