Yes or No
Domain Range

Please explain your answer, when as you see each number under Domain is 5, 6, 7 is related to one number under the Range 5 related to -2, 6 related to 0, 7 related to 4

I apologize for the confusion. Based on the given information, it appears that each number under the Domain is indeed related to one number under the Range. Therefore, this can be considered a function.
