Answer 1

ok well the range means the distance of the y values
Lets list of the y values in the current relation.
In any set of points the first value is an x value coordinate and teh second point is the y-value coordinate so it looks like this (x,y)
So looking at our points we have
(-2,3) --> y-value is 3
(5,-1) --> y-value is -1
(0,3) --> y-value is 3
(5,-2) --> y-value is -2
So all y-values are in the set of the range. The set of range is basically the set off all y-values in the relation
Range={-2,-1,3}
So which of the following provided options are in the set of the range?

Answer 2

-2 -1 and 3

Answer 3

Correct :)
