Determine the domain and range of the relation R defined by

Question:

Determine the domain and range of the relation $R$ defined by $R=\{(x, x+5): x \in\{0,1,2,3,4,5\}\}$.

Solution:

$R=\{(x, x+5): x \in\{0,1,2,3,4,5\}\}$

$\therefore R=\{(0,5),(1,6),(2,7),(3,8),(4,9),(5,10)\}$

$\therefore$ Domain of $R=\{0,1,2,3,4,5\}$

Range of $R=\{5,6,7,8,9,10\}$
