Question

look at this table:

x	y
7	-15
15	13
3	9
12	-16

is this relation a function?
options: yes, no

Explanation:

A relation is a function if every input (x-value) has exactly one corresponding output (y-value). Checking the table, each x-value (0, 7, 15, 3, 12) appears only once, with no repeated x-values paired with different y-values.

Answer:

yes
