Are you saying:
A graph with four points plotted is shown. The points are (-4,-1), (-1,4) , (1,1) , (4,1) etc ???
Why not just type it like that ?
I don't think anybody is going to wade through all this type of post trying to figure out what you are saying.
Find the domain and range of the relation and determine whether it is a function.
A graph with four points plotted is shown. The points are located at left parenthesis negative 4 comma negative 1 right parenthesis, left parenthesis negative 1 comma 4 right parenthesis, left parenthesis 1 comma 1 right parenthesis, left parenthesis 4 comma 1 right parenthesis.
A. Domain: Left brace negative 4 comma negative 1 comma 1 comma 4 right brace; Range: Left brace negative 1 comma 1 comma 4 right brace; Yes, the relation is a function.
B. Domain: Left brace negative 4 comma negative 1 comma 1 comma 4 right brace; Range: Left brace negative 1 comma 1 comma 4 right brace; No, the relation is not a function.
C. Domain: Left brace negative 1 comma 1 comma 4 right brace; Range: Left brace negative 4 comma negative 1 comma 1 comma 4 right brace; Yes, the relation is a function.
D. Domain: Left brace negative 1 comma 1 comma 4 right brace; Range: Left brace negative 4 comma negative 1 comma 1 comma 4 right brace; No, the relation is not a function.

in any case, the domain is the set of all the 1st coordinates and the range is the set of all the second coordinates.
It is a function if each domain element is used exactly once.
