Question

The figure shows a relationship between the sets $P$ and $Q$. Write this relation in
(i) in set-builder form (ii) roster form

Answer 1

The relation mentioned in the figure shows, $P$ a domain and $Q$ as range.

Let the relation be $R$

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

In set builder form $R=\left\{\right(x,y):x\in P,y\in Q,y=x-2\}$
