#### Answer

The pair of functions graphed are inverses of each other.

#### Work Step by Step

The red graph contains the following points: $(0, 3)$ and $(4, 0)$.
The blue graph contains the following points: $(3, 0)$ and $(0, 4)$.
Notice that:
$(0, 3)$ and $(3, 0)$ are 'inverses' of each other
$(4, 0)$ and $(0, 4)$ are 'inverses' of each other
Note also that the graphs are reflections of each other with respect to the line $y=x$.
Therefore, the pair of functions graphed are inverses of each other.
