Question

Use a mapping diagram to determine whether the relation is a function

(2,5), (1,9 ),(1,7),(9,8),(3,14),(2,2)


Is the relation a function?

Yes or no

Answer 1

Yes it is a function because every x has an equal y

Answer 2

No, it is not a function because if you drew any vertical line it would intersect the points (lines) more than once. Basically, the points plotted intersect themselves if you connect all of them on a graph

Explanation:

To show your work and understand it more type in Desmos graphing calculator on Google and type in the points and they will then appear on the graph. Hope this helps
