If `A={1,2,3,4,5}`, then find the domain in the relation from A to A by `R={(x,y):y=2x-1}`.

A

`{1,2,3}`

B

`{1,2}`

C

`{1,3,5}`

D

`{2,4}`

Text Solution

Verified by Experts

The correct Answer is:
A
Since, `A={1,2,3,4,5}`
`:." Relation from A to A by"`
`R={(x,y):y=2x-1}={(1,1),(2,3),(3,5)}`
`:." Domain "={1,2,3}`
