Answer:
D: {-5, -2, 1, 2}
R: {-4, 0, 3}
The relation is a function
Step-by-step explanation:
Given:
5) Ordered pairs on a coordinate plane
To find:
the domain, range, and the type of relation
![\begin{gathered} The\text{ domain is the input of a funcion \lparen x values\rparen} \\ The\text{ range is the output of the function \lparen y values\rparen} \end{gathered}]()
To determine the domain and range, we will list the ordered pairs:
(-5, 3), (-2, -4), (1, 0), (2, 3)
The first number in each pair represents the x values (domain), while the 2nd number in each pair represents the y values (range)
The domain: {-5, -2, 1, 2}
The range: {3, -4, 0, 3}
Rearranging and picking one of the repetitions:
The range: {-4, 0, 3}
For a relation to be a function, each input will have only one output.
None of the inputs appears more than once. Hence, each input has only one output. It is a function
