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

Answer: Choice A) {-4, -1, 3, 5, 6}

The domain of a relation is the set of possible x inputs. All we do is list the x coordinates of the given points. The order doesn't matter but your book has decided to list the x values from smallest to largest.

Side note: the list of possible output y values is known as the range.

Answer 2

Answer:it’s answer A, or {x | x = –4, –1, 3, 5, 6}.
