Answer: Choice D
Domain: {-3, -1, 2, 4, 6}
Range: {-2, 1, 2, 4, 6}
===========================================
Explanation:
The domain is the set of possible x values of a relation or function. To form the domain, we just list out the x coordinates of each point
Point A is located at (-3, 4) so the x coordinate x = -3 is part of the domain
Point B is at (-1,1) meaning x = -1 is also part of the domain
And so on. Doing this for all five points leads to the list of x coordinates {-3,-1,2,4,6} which is the domain.
--------------------
The range is a similar story, but we look at the y coordinates now. Point A has y coordinate 4, so y = 4 is part of the range.
Point B has y coordinate y = 1, so that is also part of the range.
The range is {-2, 1, 2, 4, 6} representing all of the possible y values of this relation.
With any set, the order does not matter. Though convention is to list the items from smallest to largest.
