Question

What is the domain of the given function?

{(3, –2), (6, 1), (–1, 4), (5, 9), (–4, 0)}

{x | x = –4, –1, 3, 5, 6}
{y | y = –2, 0, 1, 4, 9}
{x | x = –4, –2, –1, 0, 1, 3, 4, 5, 6, 9}
{y | y = –4, –2, –1, 0, 1, 3, 4, 5, 6, 9}

Answer 1

Domain = {x | x = –4, –1, 3, 5, 6}

Explanation: the domain is the set of all first components (x-values) of the ordered pairs: 3, 6, –1, 5, –4.
