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.

$R_2$ = "is one more 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 one more than the 2^ndcomponent.

$\therefore R=\left\{\right(4,3),(5,4),(6,5),(7,6\left)\right\}$
