Question

The figure given below shows a relation from $P$ to $Q.$ Complete the Range = {-2, 2, -3, 3, -5, 5, -6, __}from the diagram given?

• A. 6

Answer 1

The correct option is A 6
From the arrow diagram, it is clear that $R=\left\{\right(9,3),(9,-3),(4,2),(4,-2),(25,5),(25,-5),(36,6),(36,-6\left)\right\}.$
$\Rightarrow xRy$ means $x$ is the square of $y,$ where $x\in P$ and $y\in Q.$
Also, domain of $R=\{9,4,25,36\}.$
$\text{Range of}R=\{-2,2,-3,3,-5,5,-6,6\}$
