The figure shows a relation between the sets $P$ and $Q$. Write this relation in set-builder form. What are its domain and range?

(N/A) From the figure,we observe the following mappings:
$9$ $\rightarrow 3, 9$ $\rightarrow -3$
$4$ $\rightarrow 2, 4$ $\rightarrow -2$
$25$ $\rightarrow 5, 25$ $\rightarrow -5$
This indicates that each element $x$ in set $P$ is the square of the corresponding element $y$ in set $Q$.
$1.$ Set-builder form:
$R = \{(x, y) : x = y^2, x \in P, y \in Q\}$
$2.$ Domain:
The set of all first elements of the ordered pairs in $R$ is $\{4, 9, 25\}$.
$3.$ Range:
The set of all second elements of the ordered pairs in $R$ is $\{-5, -3, -2, 2, 3, 5\}$.
