Question

look at this table:

x	y
-3	-16
2	5
18	6
13	16
-14	16

is this relation a function?
options: 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

Verify all x-values: 10, -3, 2, 18, 13, -14. Each x-value appears only once, so each has one corresponding y-value.

Answer:

yes
