Question

consider the set A={3,6,8,9]
and B=[2,5,7]
:) find AXB

3) Write the relationR
satisfying the
condition x>y
11) Find the domain and range of R​

Answer 1

$Set \: A = \{ 3,6,8,9 \} ,\\B = \{ 2,5,7 \}$

$\blue { A \times B } \\= \{ (3,2),(3,5),(3,7),(6,2),(6,5),(6,7),(8,2),(8,5),(8,7),(9,2),(9,5),(9,7)\}$

$\pink { R} = \{ (6,2),(6,5),(6,7),(8,2),(8,5),(8,7),(9,2),(9,5),(9,7)\}$

$\green {Domain \:of \:R}\\ = First \: Co-ordinates \:of \: R\\= \{ 6,8,9\}$

$\orange {Range \:of \:R}\\ = Second \: Co-ordinates \:of \: R\\ = \{ 2,5,7 \}$
