Which relation
Describes a function?
{(0, 0), (0, 2), (2,0), (2, 2)} (a)

{(-2, -3), (-3, -2), (2, 3), (3, 2)} (b)
{(2,-1), (2, 1), (3, -1), (3, 1)(c)

{(2, 2), (2, 3), (3, 2), (3, 3)}
(D)

Respuesta :

B is the correct answer. A trick to determine a function in a set is to look at the x value. If it repeats than the set is not a function. Hope this helps!

{(-2, -3), (-3, -2), (2, 3), (3, 2)} (b)

Correct

{(−2, −3), (−3, −2), (2, 3), (3, 2)}

A function is a set of ordered pairs such that for each domain element there is only one range element. The set of ordered pairs {(−2, −3), (−3, −2), (2, 3), (3, 2)} is the only set that does not pair a domain element with two or more range elements.
