Question

Express each relation using the representations provided (table, graph, mapping). Identify the domain and range and state of each relation is a function and why. 1. ((-2,5).(-1,1).(3.1).(-1.-2)} y Domain: un Range This relation a function because

Answer 1

See explanation below

Step-by-step explanation:

((-2,5).(-1,1).(3.1).(-1.-2)} = (x, y)

The first numbers are the x values (domain)

the second numbers are the y values (range)

Domain= (-2, -1, 3, -1)

Range = (5, 1, 1, -2)

The relation is not a function because there are two outputs for one of the domain.

The domain (-1) has two outputs (1 and -2)
