What do you call two surjective functions that have the same codomain?

Let $f$ be a surjective function from $D_f$ to $C$, and let $g$ be a surjective function from $D_g$ to $C$ such that $C = \{ f(d) | d \in D_f \} = \{ g(d) | d \in D_g \}$. Assume $f \neq g$. Is there a standard term to describe this relationship? Are they symmetric perhaps?
