which of the following ordered pairs is a function.
set a: (-1,0), (-2, 1), (4, 3), (3, 4)
set b: (1, 4), (2, 3), (3, 2), (4,1)
set c: (2, 1), (3, 2), (2, 3), (1, 4)

Set a

Step-by-step explanation:

An ordered pair is a point on an x-y coordinate graph with an x and y-value. For example, (2, -2) is an ordered pair with 2 as the x-value and -2 as the y-value. When given a set of ordered pairs, ensure that no x-value has more than one y-value paired to it. When given the set of ordered pairs [(2, -2), (4, -5), (6, -8), (2, 0)], you know that this is not a function because an x-value -- in this case -- 2, has more than one y-value. However, this set of ordered pairs [(1,4),(2,3),(3,2),(4,1),] is a function because a y-value is allowed to have more than one corresponding x-value. You can also go to the website desmos and write each set and you can see which one is a function.
