Which set of ordered pairs represents a function? (1 point) A) {(0, 1), (1, 3), (1, 5), (2, 8)}

B){(0, 0), (1, 2), (2, 6), (2, 8)}

C) {(0, 0), (0, 2), (2, 0), (2, 4)}

D) {(0, 2), (1, 4), (2, 6), (3, 6)}

The very last set

{(0, 2), (1, 4), (2, 6), (3, 6)}.

The reason why is because of the vertical line test. If there are two y-coordinates on a x-coordinate then it is not a function. A function is that each x-coordinate has a y-coordinate with the x-coordinates being different.

Example is above. If you have any questions then leave a comment. Good luck!

Step-by-step explanation:

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
