The correct option will be...
Domain = {[tex]-4, -1, 1, 4[/tex]} ; Range = {[tex]-1,1,4[/tex]} ; Yes, the relation is a function.
Explanation
From the given graph, the co ordinates of the points are (-4, -1), (-1, 4), (1, 1) and (4, 1)
Domain is the set of values of x coordinates and Range is the set of values of y coordinates.
So, Domain = {[tex]-4, -1, 1, 4[/tex]} and Range = {[tex]-1,1,4[/tex]}
As we can see the graph that not more than one point lies on the same vertical line, that means the relation satisfies the vertical line test.
Thus, the relation will be a function.
