Answer:
C) (3, 1) and (3, 2); The same x-value has different y-values.
Step-by-step explanation:
The given ordered pairs are:
{(0, 0.5), (0.5, 1), (3, 1), (1, 6), (3, 2)} A) (0.5, 1) and (0, 0.5)}
This relation is not a function because there is an x-value having two different y-values.
This occurred in (3,1) and (3,2).
This will cause a vertical line to intersect the graph of this relation at more than one point. Hence it fails the vertical line test.
The correct answer is C
