State the domain of the following relation and state whether it’s a function.

Answer:
B.
Step-by-step explanation:
The Domain is {-8, - 3, 1 , 4} and it is not a function because the value 1 maps on to 2 and -5. A one-to-many relation is not a function.
For this case we have a series of ordered pairs of the form[tex](x, y)[/tex].
We have that it is not a function because the same value of the starting set has two values in the arrival set. These are:
[tex](1,2)\ and\ (1, -5)[/tex]
For its part, the domain is given by all values of x, these are:
-8,1, -3 and 4.
Answer:
Option B
Domain: {- 8,3,1,4}; No
