I believe this is only -4 and -3 because those are the only one we can decipher, but I am not sure if there is another way..
WHICH POINTS THAT ARE IN THE RANGE OF THE FUNCTION GRAPHED
"Range" refers to the y values covered by the graph....these are [ -3, 6 ]
The y values - not "points" - in this range are ( -3, 0, 1, 5 )
Oh!!! I understand now! It means the Y values, from one to another!! Thanks!
