PLEASE ANSWER THIS

Answer 1

Answer:

(A)

Step-by-step explanation:

In a function, each value of X is related to ONE y value.

To identify a function, check if the x values repeat. If they do not, then the relation is a function.

Answer A's domain is [4,5,6,7]. The x values do not repeat, so A is a function.

B, C, and D all have repeating x values in the domain.
