Question

look at this table: (table with x and y values: x=12,y=12; x=15,y=5; x=4,y=8; x=10,y=14) is this relation a function? yes no

Explanation:

A relation is a function if each input (x-value) has exactly one corresponding output (y-value). Looking at the table, every x-value (17, 15, 4, 10) appears only once, meaning each has a unique y-value.

Answer:

yes
