Question

Let P = {3, 4, 5, 6} and Q = {3, 4, 5, 6, 7}. Find the following relation from Q to P. For the case, draw an arrow diagram to represent the relation.

$R_1$ = "is two less than"

Answer 1

$P=\{3,4,5,6\}$

$Q=\{3,4,5,6,7\}$

R is the set of all ordered pairs whose 1^st component is two less than the 2^ndcomponent.

$\therefore R=\left\{\right(3,5\left)\right(4,6\left)\right\}$
