Question

The domain of the following relation: R: {(-4, 8), (8, 10), (5, 4), (1, 6), (5. -9)} is

{8, 10, 4, 6, -9)
{-4, 1,5,8)
{-4, 8, 5, 1,5)
No domain exists

Answer 1

{-4, 1, 5, 8 }

Explanation:

`(x,\ y)\\\\Domain:x\\Range:y\\\\\text{We have the relation:}\\\\R=\{(\bold{-4}, 8), (\bold{8}, 10), (\bold{5}, 4), (\bold{1}, 6), (\bold{5}, -9)\}\\\\\text{The domain is:}\ \{\bold{-4,\ 1,\ 5,\ 8}\}\\\\\text{The range is:}\ \{-9,\ 4,\ 6,\ 8,\ 10\}`
