a={(x,y):y=e^​2xx=R}

b={(x,y):y=e^​-2x​x=R}

find a intersection b

1.not a set

2.empty set

3.singleton set 4.none of these answer with reason

​

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)

Hencdc a singleton set
