A function $f(x)$ is graphed in plane A. It is clearly a 1:1 function, so it must have an inverse.
Enter the color ("red", "green", "blue", or "yellow") of this inverse function which is graphed in plane B. Use what you know about the graphs of inverse functions rather than algebraic calculations based on what you might guess the function to be.
Color of $f^{-1}$ graph $=$
