Which of the sets of ordered pairs represents a function? A= (-5,5), (-2,2), (2,-2) , (5,-5), B= (4,2), (3,-2), (9,4), (11,-3)

b does because the x does not repeat

Step-by-step explanation:

with A it is not a functions because the x does repeat because if you put function a on a graph and you draw which every way it is going whether it is a strait line or not and if your "line" lines up with another line and it the second line goes right through the twice then it is not a function

I hope this helps because i am doing this topic now in class

24

step-by-step explanation:

if it takes 8 pounds to make 12 divide 12 by 8 and you get 1.5, 1.5 x 16 = 24

answer: yes, since the line has a steeper rate of change than the exponential the y-values will be greater and they will only intersect one time.
