Question

If A={1, 2,3,4,5} B={4,6,9}. Define a relation R fr A to B by R={(X, Y) :the difference of x and y is odd:x€A, y€B} . Write R in ROSTER form​

Answer 1

Answer:

Given that,

R={(a,a

2

)/a is a prime number less than 15}

To find

Domain of R=?

Range of R=?

Roster form =?

Solution: a is a prime number less than 15

then a=2,3,5,7,11,13

Roster form ={(2,4),(3,9),(5,25),(7,49),(11,121),(13,169)}

Now,

Domain of R={2,3,5,7,11,13}

Range of R={4,9,25,49,121,169}.
