Solution

Solution Steps

Step 1: Determining the Domain

The domain of the given relation is the set of all first elements from the ordered pairs. Thus, the domain is $\{11, 20, 42, 57\}$.

Step 2: Determining the Range

The range of the given relation is the set of all second elements from the ordered pairs. Thus, the range is $\{-7, 4, 5\}$.

Step 3: Checking if the Relation Represents a Function

The relation does not represent a function because there exists at least one input (domain element) that is associated with more than one output (range element).
