Question

1. look at this table;

x	y
7	16
-7	19
7	3

1. is this relation a function?

1. yes no

Explanation:

A relation is a function if each input (x-value) has exactly one corresponding output (y-value). In the table, the input value 7 appears twice, paired with two different output values (16 and 3). This violates the definition of a function.

Answer:

NO
