The domain and range of the relation

\mathrm{R}

given by

R=\left\{(x, y): y=x+\frac{6}{x}\right.

; where

x, y \in N

and

x < 6\}

View answer and explanation

Correct option: A

\{1,2,3\},\{7,5\}

Option A ({1,2,3},{7,5} ) is correct because it correctly identifies the domain and range of the given relation by substituting the values of x and finding the corresponding y values.
