If the sets A and B are defined are defined as `A={(x,y):y=e^x, x in R},B={(x,y):y=x, x in R}`then
a. `B sub A`
b. `A sub B`
c. `A nn B = phi`
d. `A uu B`

A

`B sub A`

B

`A sub B`

C

`A nn B = phi`

D

`A uu B`

Text Solution

Verified by Experts

The correct Answer is:
B
`A = {(x,y):y=e^(x),x inR}`
`B = {(x, y):y=x,x inR}`

`therefore A sub B`
