Three points are shown on $y = f(x)\text{.}$ For each point, switch the $x$- and $y$-coordinates, and move one of the free points to that location. If the points are correctly placed, the graph of $y = f^{-1}(x)$ will appear, together with the dashed line $y = x\text{.}$

1. Did you correctly place the points?
   Answer: ? No Yes
2. How are the graphs of $y = f(x)$ and $y = f^{-1}(x)$ related?
   Answer: They are reflections over the ? line y = x x-axis y-axis
