1. If the graph of the function $y=f(x)$ passes through the point $(0,1)$, then the graph of the inverse function of $y=f(x+4)$ must pass through the point $\qquad$
1. $(1,-4)$.
The graph of $f(x)$ passes through the point $(0,1)$, so the graph of $f(x+4)$ passes through the point $(-4,1)$, and its inverse function's graph passes through the point $(1, -4)$.
