Find the domain and range of the relation and determine whether it is a function.

The correct option will be...

Domain = {} ; Range = {} ; 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 = {} and Range = {}

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.
