Question

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

Answer 1

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.

Answer 2

For this case we have a series of ordered pairs of the form$(x, y)$.

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:

$(1,2)\ and\ (1, -5)$

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
