A) \[A\cap B=\phi \]
B) \[A\cap B\ne \phi \]
C) \[A\cup B={{R}^{2}}\]
D) None of these
Correct Answer: B
Solution :
Given sets are \[A=\{(x,\,\,y)y={{e}^{x}},\,\,x\in R\}\]and \[B=\{(x,\,\,y):y={{e}^{-x}},\,\,x\in R\}\] It is clear from the graph that two curves intersect at one point. \[\therefore \] \[A\cap B\ne \phi \]You need to login to perform this action.
