For each relation below, determine the following.(i) Is it afunction? If not, explain why not and stop. Otherwise, answer part(ii).(ii) What are its domain and image?
(a){(x, y) :x, y?Z, y- 2x}.
(b){(x, y) :x, y?Z, xy- 0}.
(c){(x, y) :x, y?Z, y-x2}.
(d){(x, y) :x, y?Z, x|y}.
(e){(x, y) :x, y?Z, x+y= 0}.
(f){(x, y) :x, y?R, x2+y2= 1}.
