Answer:

[tex]D = \{-2,-1,3,5\}[/tex] -- Domain

[tex]R = \{-7,0,4\}[/tex] -- Range

It is a function

Step-by-step explanation:

Given

[tex]D = \{-2,-1,3,5\}[/tex]

[tex]R = \{-7,0,4\}[/tex]

Required

State the domain and range

Determine if the relation is a function

From the question, we have the domain and range as:

[tex]D = \{-2,-1,3,5\}[/tex] -- Domain

[tex]R = \{-7,0,4\}[/tex] -- Range

Next, is to determine if the relation is a function or not.

Yes, it is a function.

The number of elements in the domain is 4

The number of elements in the range is 3

When the domain has more elements than the range, this is called a many-to-one function, and it is a valid type of function.
