Question

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

Answer 1

The correct option will be...

Domain = {
`-4, -1, 1, 4`} ; Range = {
`-1,1,4`} ; Yes, the relation is a function.

Step-by-step 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 = {
`-4, -1, 1, 4`} and Range = {
`-1,1,4`}

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.
