Solution:
The domain is the set of independent values of a relationfor which the reltion is valid.
The range is the set of dependent values of a relation for which he relation is valid and real
Given:
From the above image, we have
[tex]\begin{gathered} Domain:\text{ -2, 3} \\ Range:\text{ 4, -2, 0, 2} \end{gathered}[/tex]
For a relation to be a function, for every value of x there is only one corresponding value for y.
Since the value of domain in the above figure outputs more than one value, the relation is not a function.
Hence, the correct answer is NO
