{(-1, 1), (-2, 1), (-2, 2), (0, 2)}

Yes; there is only one range value for each domain value.

Answer: The answer is letter B "No; a range value has two domain values".

For a relationship to be a function, there must be a one-to-one correspondence between the x and y values. For every value of x, there must be only one value for y. So the first set is a function and the second set is not.

Answer:

No; a range value has two domain values.

Step-by-step explanation:

Output has to be unique for all inputs.

Output for -2 is not unique

Step-by-step explanation: It is either B or C

Since

x = − 2

produces

y = 1

and

y = 2 , the relation

( − 1 , 1 ) , ( − 2 , 1 ) , ( − 2 , 2 ) , ( 0 , 2 )

is not a function.

The relation is not a function.

Answer:

No; a range value has two domain values
