Answer
The pair of functions graphed are inverses of each other.
Work Step by Step
The red graph contains the following points (approximation only): $(0, -2.5)$ and $(1.25, 0)$.
The blue graph contains the following point (approximation only): $(-2.5, 0)$ and $(0, 1.25)$.
Notice that:
$(0, 1.25)$ and $(1.25, 0)$ are 'inverses' of each other
$(-2.5, 0)$ and $(0, -2.5)$ 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.
