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}
