Answer:
Problem 1: No
Problem 2: Yes
Step-by-step explanation:
Problem 1:
{(-2, 1), (-2, 3), (0, -3), (1, 4), (3, 1)}
This relation is not a function because there are two y-values, 1 and 3, related to one x-value, -2.
Thus, for a relation to be a function, every x-value must be related to exactly 1 y-value.
Problem 2:
{(0, 2), (3, 4), (-3, -2), (2, 4)}
In this relation, each x-value (domain) has exactly one y-value (range) that it is related to. Therefore, this is a function.

Answer:
if you have a vertical line with 0 in the middle, the number above zero will be positive numbers That will be above sea level. The number below the zero will be negative numbers which are below sea level.
so the 2.5 below sea level will be in the negative side (below the zero) between -2 and -3.
I hope this can help.
