Find the domain and range of each relation. Then determine if the relation is a function. D={-2, -1, 3, 5}, R={-7 ,0 ,4} Function?

-- Domain

-- Range

It is a function

Step-by-step explanation:

Given

Required

State the domain and range

Determine if the relation is a function

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

-- Domain

-- 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.
