Answer
$R=\{ (-3,4),(-3,1),(2,0) \}$
Work Step by Step
$\bf{\text{Solution Outline:}}$
Use the ordered pair notation of relations which is given by
\begin{array}{l}\require{cancel}
R=\{ (x_1,y_1),(x_2,y_2),(x_3,y_3),... \}
.\end{array}
$\bf{\text{Solution Details:}}$
In terms of a set of ordered pairs, the relation in the given diagram is equivalent to
\begin{array}{l}\require{cancel}
R=\{ (-3,4),(-3,1),(2,0) \}
.\end{array}
