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.
