Given: B = {(4,2), (4, -2), (16,4), ...} Is B a function and why? A. Yes, each set of ordered pairs in this list has no repeat of a range element.

B. No, the number 4 is an element in the domain and range.

C. Yes, there is more than one ordered pair in this list.

D. No, two ordered pairs in this list have a repeat of the domain element.

D. No, two ordered pairs in this list have a repeat of the domain element.

Step-by-step explanation:

A function is a set of ordered pairs in which no two different ordered pairs have the same x -coordinate (the domain element).

So B is not a function because two different ordered pairs have the same x -coordinate: (4,2), (4, -2)

Therefore answer D is correct.

i got 86 for this

hope this !

if you need an explanation just ask

care to share were the trapezoid shown is ?
