Question

algebra 1 > m.4 identify functions vll
look at this table:

x	y
-14	18
15	18
-20	14
14	9
9	14
15	-12

is this relation a function?
yes no

Explanation:

Step1: Recall function definition

A relation is a function if each input (x - value) has exactly one output (y - value).

Step2: Check x - values for uniqueness of y - values

Look at the x - value 15. In the table, when x = 15, we have two different y - values: 18 and - 12. Since one input (x = 15) is associated with more than one output, the relation does not satisfy the definition of a function.

Answer:

no
