Question

A={(x,y):y=e 2x ​x=R}​ B={(x,y):y=e ​-2x x=R}​ ​1. . ​not a set 2.singleton set 3.empty set 4.none of these

Arun · Answer

y=e x here x can vary from - infinity to + infinity but y can be only positive number so A = {R,positive number} and for y = e -x x can vary from - infinity to + infinity but y can be only positive number so B = {R,positive number} so A intersect B at only (0,1) Hence A intersection B is (0,1) Hence a singleton set
