#### Answer

$\text{
a function
}\\\text{Domain: }
\{ 4,9,11,17,25 \}
\\\text{Range: }
\{ 14,32,47,69\}$

#### Work Step by Step

$\bf{\text{Solution Outline:}}$
If each first component in the given diagram is paired to only $1$ value, then it is a function. The domain is the set of all first components and the range is the set of second components.
$\bf{\text{Solution Details:}}$
Since each of the first component is paired to only $1$ value, then the given diagram is a function.
The domain is the set of all first components and the range is the set of second components.
Hence, the given set has the following characteristics:
\begin{array}{l}\require{cancel}
\text{
a function
}\\\text{Domain: }
\{ 4,9,11,17,25 \}
\\\text{Range: }
\{ 14,32,47,69\}
.\end{array}
