Question

For which value of x is the relation not a function (5,2), (x,1), (8,6), (9,3)

Answer 1

x=5, 8, 9

Explanation:

in a function, one x value must be paired with one and only one y value, this means there cannot be two points where x values are the same, however the y values can repeat.

if x = 5, 8, or 9, the relation is not a function because there are 2 same x values.
