If `A={1,2,3},\ B="{"1,4,6,9"]"a n d\ R` is a relation from A to B defined by `x` is greater than `ydot` The range of `R` is
A.`{1,4,6,9}`
B. `{4,6,9}`
C. `{1}`
D. none of these
ANSWER: C

Text Solution

Verified by Experts

Given
`A={1,2,3},\ B="{"1,4,6,9"]"`
so,`R={(x,y):x inA,yinB and x>y}`
Thus R can be expressed as
`R={(2,1),(3,1)}`
Therefore, `R={1}`
