What’s the domain and range for this? Thanks!

Domain is the x value (here,y) and the range is the y value (x,here).
To answer your problem we know that the coordinates are (-5,1) and (5,-1) -5 and 5 are in the domain spot (x) while 1 and -1 are in the range spot (y).
Your answer would be Domain: {-5,5} and Range: {1,-1}.
